hells - Steel pipe to ASME specification. Shells are shot blasted and cleaned prior to assembly.
Tubes - Copper high performance enhanced design, roller expanded into multiple-grooved tube sheet.
Tube sheet - Flange quality steel to ASME specifications. Precision machined for excellent sealing.
Baffles - Hot-rolled steel for enhanced strength and reliability. Engineered for correct fit to reduce tube wall damage from high velocity fluids.
Heads - Fabricated to ASME specifications using steel ring and cover design with superior gas distribution.
Connections - Fluid connections 3" IPS and smaller terminate as MPT type. Fluid connections 4" IPS and larger terminate in 150 Lb. ANSI raised face. refrigerant connections are steel and bored to ODS of copper tubing. Thermowell, vent and drain are provided.
Codes - The refrigerant side is constructed to the latest edition of the ASME Section VIII Div. 1 code and stamped accordingly. Refrigerant side pressure is designed for 250 PSI at 100F. Shell side design pressure is 150 PSI at 120F. Both circuits are tested at 1.25 times the design pressure under water and dried prior to sealing.

DC Series Desuperheater

  • Length 40-1/2 "
  • Weight 2-3/4 "
  • TR 5 tons
  • Refrig. Conn 1-1/8" ID
HEAT RECOVERY UNIT FOR DOMESTIC HOT WATER FROM AIR CONDITIONING AND REFRIGERATION SYSTEMS UP TO 100 TONS

DC Series Chemically Cleanable Commercial Desuperheaters recycle rejected heat from your air conditioning or refrigeration system and use it to heat water or other fluids. At the same time, desuperheating lowers refrigerant temperature and pressure, reducing energy input to the compressor. You save by reducing or eliminating the energy required for water heating while increasing the efficiency of the air conditioningrefrigeration system.

Suction Line Heat Exchangers

  • HP 1
  • Gas Conn 5/8 "
  • Liquid Conn 3/8 "
  • Length 13 3/4 "
For enhanced evaporator capacity, system stability, compressor protection and oil return.

>Nominal SLHE selections should be based on system horsepower, which will provide a nominal 10F subcooling and a nominal 20F suction superheat for R-22, R-502, R-404A, R-507, R-407A, R-504, R-134A, R-407C and R-410A at 110F condensing and 25F suction. For example, for a 1-12 HP system, select an SLHE 1-12. Do not select undersized models to avoid high suction pressure drops and gas whistling.

Selections based on suction and liquid line sizes are appropriate for standard low, medium and high temperature refrigeration systems provided the system HP rating closely matches the SLHE selection.

Selection of oversized models will provide additional liquid subcooling and suction superheat. Oversized models are acceptable only if the suction gas temperature to the compressor is not raised above 65F for proper compressor performance.

Standard and custom models can be selected by Doucette to meet any performance criteria, up to 60F subcooling. For exacting subcooling and superheat performance please contact the factory.
