Product Description

Series HLEX - Hot gas bypass valves with fixed orifice, balanced port, external pressure equalisation and adjustable suction pressure limitation.
Hot gas bypass valves series HLEX are used to adjust the compressor capacity to the actual evaporator capacity in a refrigerating plant. The hot gas bypass valve can be installed in a bypass tube between the hot gas line and suction line. The suction pressure is downward limited by flowing hot gas from the high pressure to the low pressure side. For plants in general refrigeration and for original equipment such as dehumidifiers, air driers, water coolers or ice-making machines.
  • Compact design
