RM Series – Rack Mounted / Air or Water Cooled Wine Cellar Refrigeration Units
Single & Twin Evaporator Units with Digital Controller
SYSTEM INFORMATION
The Rack Mounted (RM) Systems are optimized to deliver refrigeratedair sufficient for medium-hightemperature locations - custom wine cellars, wine tasting rooms and large cabinets.RM series evaporators mount horizontally, often within the wine racking. These unitshave several access panels toforward or re-direct the supply andreturn vents. These can also be placedbetween ceiling joists,in a soffit, or on a wall. For good reason amongst the various wine room refrigeration units we manufacture this is the most versatile and therefore our most popular.
RM evaporators are offered instandard capacities from 2,600 to6,600 BTU per hour and are usedwith R134a refrigerant.
OPTIONS
- Evaporatorsystems come in either twin or triple configurations ideal for larger applications
- Eco-friendly water-cooledcondensing units are available
- Eco-friendly water-cooledcondensing units are available
FEATURES
- Coils are staggered with mechanically expanded copper tubing in aluminum fins for particularly high-performance
- Aluminum housing is insulated and rust-proof
- Permanently lubricated motor is thermally protected
- Automatic expansion valve (as standard) this ensures a constant coiltemperature which promotes "Humidity Balance"
- Pump-down solenoid valve (as standard) protects compressor in the event of leaks
- Additional wiring to thermostateliminated by pre-installed valves
- Manufacturer pressure tested to ensure quality
- Factory wired for simple field installation
- ETL certified

RM Cooling System Typical Installation
- Keep line sets as short as possible.
- Excessive number of turns will cause refrigerant flow problems. This could cause early compressor failure. Suction line accumulators are recommended. Required if working lower than the normal 55-65° operating range from wine cellar.
- Drain line must always flow downhill to drain or pump.
- The system is controlled by a pump down control system. There is no control wiring between thermostat and condensing unit.
- The line connections at Fan Coil and Condensing Unit may not be the same as the required line sizes.
- Standard line sets should be 50' or less. Extended runs may require larger line sizes and 3oz oil must be added for every 10' over 35'.
RM Fan Coil Specifications
- It is best to use the larger coil whenever possible.
- If using a smaller coil a suction line accumulator must be used
- Smaller coils can cause the system to run a lower humidity
- Expansion valve and liquid line solenoid valve standard
- For air flow into and out of the unit, at least one access door must be removed from each end
- Connections at coil do not indicate refrigeration line size. See system information for line sizing
