Frigoboat Sets the Standard in Marine Refrigeration

With several different compressor models available, Frigoboat is capable of cooling refrigerator boxes of up to 20 cubic feet or freezer boxes up to 10 cubic feet.

The basics of a refrigeration system are a compressor/condenser, an evaporator and a box or area to contain the cold air. Additionally, a controller/thermostat is used to control the system, so it doesn’t just run all the time.


Compressors/Condensers

Frigoboat offers three types of compressors so there’s one for every budget.

  • Air Cooled Compressors
  • Water Cooled Compressors
  • Keel Cooled Compressors

Air Cooled Compressor/Condenser refrigeration systems use a fan to move cooing air through the condenser and provide your boat with cold food storage.

Water Cooled Compressor/Condenser refrigeration systems use an external water pump to move cooing water through the condenser for your boat’s refrigerator/freezer.

Keel Cooled Compressor/Condenser systems use a keel-cooler as the condenser to provide the best most efficient, and quiet, form of marine refrigeration.

Frigoboat Offers Three Evaporator Options

Bendable Flat Plate can be used flat or bent to fit in your refrigerator or freezer box.

The Flat Plate with Stainless Cover (Non-Bendable) is recommended if bending is not required and offers protection from hard object thanks to the steel cover.

Vertical & Horizontal Bin Type Evaporators are a pre-bent plate that forms a small freezer section in the ice box on your boat.

Frigoboat Thermostats

Frigoboat offers Manual Thermostats for refrigerators or freezers and Digital LED Thermostats. The LED thermostats include a display panel that can be mounted conveniently where you can clearly see what your refrigerator/freezer box temperature is at any time.

The Frigoboat Optional Fan Speed Control

Frigoboat’s Merlin II is a small circuit board that plugs onto the controller of your Danfoss BD35 or BD50 compressor to control the compressor speed automagically! The Merlin II includes a green LED that blinks to show at what speed the compressor is running and a red LED that blinks one to five times to tell you where to troubleshoot should your compressor stop for an electrical fault reason.

Merlin II gives you big energy savings while also protecting your system’s electronics and reducing the stress on various components.

Fire Extinguishers and your Boat

Fire extinguisherNothing causes as much concern for a boater than a fire aboard while underway. Here is what happens in a boat without an automatic engine room extinguisher. Most boat fires start in the confines of the engine room, killing engine and electrical power to the vessel. One or two 2BC extinguishers cannot put out the enclosed fire.  The fire then spreads quickly to the rest of the vessel through all the flammables that are readily available, such as the wood trim and foam cushions. Soon the very fiberglass the boat is built from is burning. Ultimately, leaving no alternative but to abandon the vessel. The vessel burns to the waterline.

The key to fighting a boat fire is done at the dock before you leave the marina.

Here are the USCG minimum requirements for fire extinguishers onboard pleasure craft

  • For boats under 26′ – At least one B-I type approved hand portable fire extinguisher.
  • For boats 26′ to 40′ – At least two B-I OR one B-II type approved hand portable fire extinguisher.
  • For boats 40′ to no more than 65′ – At least three B-I OR one B-I plus one B-II type approved hand portable fire extinguisher.

Keep in mind that these minimum requirements are exactly that; the absolute minimum. A B-I type extinguisher equals 2 pounds dry chemical. A B-II type extinguisher equals 10 pounds dry chemical. These portable fire extinguishers are also rated to the class of fire they will be able to put out.

  • Class A: Ordinary Combustibles Includes wood, paper, cushions, canvas, fiberglass, rubber, many plastics, and other materials that burn easily and account for many boat fires. These can be extinguished with water.
  • Class B: Flammable Liquids Includes gasoline, propane, diesel fuel, oils, grease, paints, tars, lacquers, and flammable gases.
  • Class C: Energized Electrical Equipment Includes wiring, fuel hoses, circuit breakers, machinery, and appliances.

You will likely be using an approved BC Class (although it may be ACB) extinguisher. Using a portable dry chemical extinguisher will allow you to fight a fire ONLY if it is in the first couple minutes of a burn and you can spray the extinguisher at the base of the fire; after that, you are using the extinguisher to fight the fire as you exit the vessel. A portable fire extinguisher should be kept handy between the galley and the exit and a second one near the engine room.

Now for the engine room. Because of it’s caustic, noxious agent, discharging a dry chemical extinguisher into a fire may cause damage or even destroy the items that you are trying to protect. There is a superior, modern extinguisher medium (agent) called FM-200. This unique product leaves no residue and is safe to discharged near any electrical or mechanical equipment. FM-200 is even safe enough for discharge in occupied spaces! FM-200 systems reach extinguishing levels in 10 seconds or less, stopping ordinary combustible, electrical, and flammable liquid fires before they cause significant damage.

For use in enclosed spaces like an engine room, there are two operation modes available for Sea-Fire FM200 systems; automatic and manual / automatic models. A Sea-Fire automatic extinguisher is activated by the attached temperature sensor valve. Discharge will occur when the sensor valve temperature rises to the system activation point as shown in the specification table and on the label attached to each unit. The manual / automatic offer the ability to lead a manual discharge cable to a position outside the enclosed compartment (often the helm station) so that the extinguisher may be operated remotely. If an automatic / manual extinguisher is not activated manually, it will work as a normal automatic model and discharge when the system activation point is reached.

Sea-Fire manufactures FM-200 FD Series manual and automatic fire extinguishers for areas as small as 175 cubic feet and up to 1500 cubic feet.  The Sea-Fire FG Series are made to fit small engine rooms an other closed areas, from 25 to 240 cubic feet. Sea-Fire also manufactures the FT Series which are supplied with long, flexible narrow tubing that can reach into hard to access areas; such as the backside of electrical panels for spaces from 25-150 cubic feet.

In summary, dry chemical fire extinguishers are fine for trying to put out a fire on the stove, heater or open area. Sea-Fire FM-200 extinguishers are useful in enclosed spaces, occupied spaces and hard to reach spaces.

Remove Salt from Your Boat, Engine and Marine Equipment

Looking for a way to remove salt from your boat and other marine equipment including boat cooling system, cleats, other metal and fiberglass parts?

Salt-Away salt removal washing concentrate uses a carefully selected blend of ingredients that will provide optimum cleaning for your boat and boat engine. Salt-Away washing concentrate provides salt removal from virtually any surface.

Salt-Away uses a water-based 100% – Non-Hazardous, Non-Toxic, and Biodegradable blend of ingredients that dissolves salt crystals from surfaces. Water alone cannot do this.

Salt-Away flushes salt from inboard/outboard engines.

Many boats have engines using a fresh water closed cooling system. Some boat owners do not realize that the raw water side of the engine, where salt water passes through the heat exchanger and out the exhaust manifold, can have major salt corrosion problems. Without proper maintenance, this corrosion leads to expensive repairs.

Salt-Away has many uses:

  • Engine flush – Can correct engine over-heating by breaking down layers of salt accumulation
  • Cleaning diving & fishing gear
  • Seaside home maintenance – A/C units, patio furniture etc.
  • Power & Sail boat salt removal – sails, sail covers, line, hardware etc.
  • Boat trailer and trailer brake wash

Salt-Away is economical to use with a dilution rate of 500 to 1 ratio.

The Salt-Away SA32M Combo Kit combines a one quart Salt-Away concentrate bottle and a 6 oz capacity, re-usable Mixing Unit. The Salt-Away Kit is recommended as the “Starter Kit” for the Salt-Away salt removal product line.

  • 6 oz Salt-Away concentrate holding capacity
  • Mixing Unit connects to
    • Garden hoses
    • Pressure Washer in lines

Salt-Away cleaning solution can be used with other Marine Engine Flushing systems and units to keep your inboard and outboard engine cooling system clean. When used with other Marine Cleaning Tools, Salt-Away removes salt build up and gets parts and surfaces ready to protect with wax or polish.

Go2marine has many more items to help boat owners care for, maintain and repair their boat. If you have questions about the care and upkeep of your boat, check our site or give us a call at (800) 998-9508

Choices and Considerations for Shower and Sump Pumps

pump

A fully-stocked modern 36-40 foot powerboat can contain more than a dozen pumps that carry out an array of tasks. Sump pumps are commonly used to move shower, sink or sump water from the utility to storage tanks in the vessel. The water will be pumped into a gray water waste tank, which can be emptied out at the dock, using another pump.

These utility pumps typically come with a built-in pressure valve that shuts down the pressurizing system when the pump reaches full pressure. Most marine pumps that move these slurry liquids are diaphragm pumps. These products contain an internal chamber with an entrance and exit, and a membrane that expands when the chamber draws in water.

The 50880 Series Jabsco sink, shower and bilge pump, is a quiet-running pump that boasts a flow rate of over four gallons per minute. It is available in either 12 or 24 DC volts and is fully resistant to corrosion.

Jabsco’s diaphragm pumps can be used to pump sump water at a flow rate of 3-5 gallons per minute, and can often be used for deck washing as well. Additionally, the unique design of this product allows for it to run dry for extended periods without damage.

Freshwater Marine Pumps: Par Max

The original Peters and Russell Pumps – PAR, by Jabsco (now a division of XYLEM)

The original PAR (Peters and Russell) belt driven diaphragm water pumps by Jabsco are the grandfather of the electric boating pumps. 80% of all boats made today will have a PAR or Jabsco pump of one kind or another on-board the vessel.

The most common use for a pump on-board a vessel is to move fresh water from a tank to the fixture or from a tank or bilge to a thruhull.

This classic belt drive Jabsco “PAR” freshwater, shower and grey water pump utilizes the original Peters and Russell (Inc., Springfield, Ohio) design that has dependably served the marine industry for nearly 50 years! In many cases parts are still available and these ‘chugging’ diaphragm pumps just keep working and working. The biggest advantages of these pumps is their ability to digest some large materials and limited dry running.

The modern Jabsco PAR-Max pump series takes a different, if not more compact approach to pumping freshwater. The PAR-Max pumps are numbered 1-4 and will serve a variety of needs.

The PAR-Max Plus is the next generation of water pumps.

The high pressure capability of the new Jabsco PAR-Max Plus Series water pressure pumps, available in 4.0, 5.0, and 6.0 GPM models, provides exceptional flow and consistent water pressure to easily handle the demand of multiple outlets. All PAR-Max Plus models include soft rubber mounts and quick connect fittings for ease of installation. The patented PAR-Max Plus co-injected molded diaphragm and larger heavier duty motor brushes significantly extend pump life up to 50% longer than existing Jabsco PAR-Max Series diaphragm pumps.

The PAR-Max Plus series is self-priming up to 10ft (3m) and can run dry without damage. It’s manufactured from corrosion resistant materials, capable of handling the harshest marine environments. Available in both 12 or 24 volt DC versions, the PAR-Max Plus series water pressure pumps are certified to EN ISO 8846 Marine (Ignition Protection).

Older generations Par-Max pumps:

The PAR-Max Series of pumps feature pressure switches as well as being conveniently sized for your application; PAR-Max 1 will service 1 water fitting, PAR-Max 4 will service 4 water fittings. The PAR-Max pumps can be used for freshwater, water transfer, wash-down. These pumps can be run dry. Rebuild service kits are available.

Jabsco also maufactures Rule Bilge Pumps and Flojet Freshwater Pumps.
