HOME

MODEL:  ST-1000-CFC

Manufactured by:  Refrigerant Recovery Systems

 

Part 1:  General

 

A.      This specification shall govern the design, fabrication, equipment, materials, text, performance, inspection and other minimum requirements of a refrigerant recovery/recycling system.

 

B.      Quality Assurance:  The manufacturer must be regularly engaged in the fabrication of engineered refrigerant recovery/recycling equipment for commercial and industrial use.

 

C.      Equipment:  All material and fabrication shall be of the highest quality available at the time of manufacturing.

 

D.      Testing:  UL or other qualified testing laboratory approved.  All components of the packaged unit and unit as an assembly shall be tested prior to shipment.

 

E.       Warranty:  Unit must have a two (2) year written warranty covering failure of materials and workmanship of all components of the fabricated packaged refrigerant recovery/recycling system.

 

Part 2:  Design:  Packaged refrigerant recovery/recycling unit shall be designed to meet and comply with the following requirements.

 

  1.  Must be capable of removing oil, moisture, acids and solid contaminates from the refrigerant being recycled.

 

  1.  Dimensions:  Approximate Weight:  130 lbs.  H 34” x W 18” x D 14”

 

  1.  Unit to be capable of handling:  R-12, R-22, R-500 and R-502

 

  1.  Approximate pump down time will be 3-5 lbs. per minute, dependent upon the amount of liquid refrigerant available and the ambient temperature.

 

  1. Location of gauges, switches, hose connections and control valves shall be easily accessible to the operator.

 

  1. Storage Tank:  Unit shall be supplied with one (1) 50 lb. D.O.T. approved refillable storage tank.  Tank to have automatic float control to safely shut system off before over filling.

  1. Must be capable of distilling refrigerant to separate the oil, acids and other contaminants from the recycled refrigerant, using a one step process.

 

Part 3:  Unit Components:  The packaged refrigerant recovery/recycling system shall be shop assembled, portable with wheel or two wheel dolly.  Unit shall be pre-piped and pre-wired at the manufacturer’s facility.

 

  1.   Compressor:  Minimum 1 HP, rotary type compressor.

 

  1.   Oil Separator:  Unit must have an oil separator for protection of the systems compressor.

 

  1.  Filters:  Unit must have two (2) cartridge type, easily replaceable filters.  Filters  to have a minimum of 62 square inches of filter surface and 35 cubic inches of desiccant in each filter.  Filter shells to be brass or steel construction.

 

  1.  Heat Exchangers:  Unit to have sufficient number of heat exchangers to vaporize refrigerant prior to entering the compressor.  Minimum capacity to be 14 lbs.

 

  1.  Waste Oil Collector:  Unit must have a large capacity collector to trap oils, acids and other residue removed from contaminated refrigerants:  14 lbs. minimum.

 

  1.  Condenser:  Unit’s condenser must be large enough to condense a high volume of vapor to liquid for storage.  Condenser shall have copper tube/aluminum fin construction and will have two (2) 10” minimum fan with electric motor.

 

  1.  High Pressure Cut-Off:  Unit must have built in safety switch to turn off system if pressure becomes excessive.

 

  1.  Liquid Vapor Valve:  Storage tank will have an approved liquid vapor valve to allow for removal of liquid without turning the tank.  Built-in pressure relief valve for safety.

 

  1.  Tubes/Fittings:  Copper tube and fittings for manifolds and condenser connections to prevent corrosion and provide longer life.

 

  1.  Service Panel:  Shall house all the electrical and mechanical requirements of the unit.  The controls and instruments required shall be suction and discharge pressure gauges, and electrical control switches.

 

  1.  Pressure Gauges:  Two gauges mounted on panel to indicate inlet operating pressure to the compressor and the liquid pressure leaving the system.
