Refrigeration Kit, Horizontal

Part #: Z3864
Refrigeration kit for the Catalina 36 and possibly others with a horizontal evaporator. Includes a horizontally mounted evaporator and a compressor unit which can be cooled by either air or water (with the addition the optional water cooling kit). This is a direct replacement for Catalina 36s and others that used a horizontal evaporator in the ice box and require no more than 15' of tubing connecting the evaporator and condenser.
Many Catalinas were equipped with Adler Barbour refrigeration at the factory. By now they are approaching the end of their life for several reasons in addition to normal wear and tear. As a result, upon failure, repair is not a realistic option. The only logical solution is to replace them with more modern versions.

Upgrades that apply to the current generation:
• The old "one shot" (read that as "one chance" to get it right) connectors in the refrigerant tubing have been eliminated. Quick connectors can now be connected and reconnected multiple times. Gone is the need to recharge the refrigerant because of a simple installation error.
• Old R-12 refrigerant has been replaced with a more environmentally friendly HFC134 refrigerant that required a redesign of the unit.
• A high-performance Danfoss BD50F compressor, with up to 25% better cooling performance than the BD35F is now standard.
• The condenser is built to accommodate water cooling. Just add a cooling water supply to increase efficiency.

Refrigeration in a Catalina has always been a bit of a challenge. Ideal locations for the condenser / compressor unit, near but above the bilge, where a cool air supply can be drawn from where the hull is in contact with the water is already occupied. Tanks, batteries and pumps preclude mounting it there. Catalina was forced to locate it in a less than ideal space, inside of the cockpit locker.

Remember, your ColdMachine doesn't create cold air. It moves the heat from the refrigerated area to the area surrounding the condenser / compressor assembly. Inside the cockpit locker, the hot air discharged from the condenser heats the surrounding air. Since it has no escape, and there is very little of the hull against the water, there is no place for the heat to dissipate. The installation manual says it best.
"Do not re-circulate the same air unless the compartment in which you mount the unit is 100 cubic feet/2.83 cubic meters or larger in volume, unobstructed, and mostly below the waterline."

The addition of water cooling to our Super ColdMachine helps mitigate the drawbacks of the mounting location. The circulating water absorbs waste heat and discharges it overboard. Simply flip a switch to turn on the circulation pump and efficiency increases. In winter, when the air in you cockpit locker remains cool, just leave the circulating pump off.

If your refrigeration has failed in the middle of the season, its not a problem. Install the new system and use it in air-cooled mode as you have been. At your next haul-out install the optional water circulation system. Next season you have even more efficient refrigeration. Includes 15 feet of pre-charged tubing, pre-charged with refrigerant.

1) Although the installation of the refrigeration system is not difficult, there is a long list of simple steps that must be completed accurately. Follow these steps in the instruction manual carefully and the unit will work great. Miss one step or complete one step incorrectly and the operation will be erratic and inefficient or perhaps not at all.
