Compressed Refrigerated Air Dryer

Unique 7x Heat Exchanger with Moisture Separator

Our 7X Heat Exchanger is the combination of Pre cooler, Evaporator and built in Stainless Steel demister moisture separator.

Pre cooler (air to air heat exchanger) and evaporator (air to refrigerant heat exchanger) are cross flow type with more cross sectional area for flow to make it non-clogging. Heat Exchanger is designed to have better turbulance & maximised heat transfer rate. Lesser difference in temperature between Inlet Air & Outlet Air ensures better effectiveness. Piping is completely eliminated and the air passage is non-ferrous. The heat exchanger assembly is encapsulated in PUF Insulation (Eco Friendly) to prevent the loss of cooling effect

SPECIAL FEATURE OF CO-EX

Tower

  • High efficiency.
  • Corrosion resistance.
  • Lesser weight.
  • Compact in size
  • Ease of access to inlet and outlet.
  • User friendly.
  • Less maintenance

DEPENDABLE AUTOMATIC CONDENSATE DRAIN WITH THE FOLLOWING FEATURES

Adjustable electronic timer controlled, Pilot operated / direct, compressed air powered, Auto drain valve.

Positive discharge of even heavily contaminated condensate.

NON-CYCLIC REFRIGERATION SYSTEM

HOT GAS BY-PASS Value automatically maintains dew point temperature across a wide range and ambient conditions without the need any adjustments. High pressure, high temperature refrigerant vapour is introduced after the expansion valve to ensure temperature control.

Direct expansion, non-cycling allows rapid response to changes in operating conditions.

INSTALLATION & SERVICE

EASE OF INSTALLATION

All dryers are shipped pre-piped and wired, ready to install and operate, installation is made easy with conveniently located Air and Drain connections.

ELECTRICAL

In accordance with applicable codes with professional harnessing & wires as per IS : 694 -1990. Compressors for larger capacity dryers are protected with overloads and safety trips.

ENVIRONMENTAL

GEM DRYERS are designed to have low energy usage, helping to conserve the Earth's Resources and minimize pollution. Refrigerants are with zero ozone depletion factor, and thereby making GEM dryers’ ‘OZONE FRIENDLY’.

SERVICE

GEM DRYERS are designed to require little maintenance. Should service be necessary, a team of trained technicians is available to answer your questions about installation, operation and maintenance or repair. A complete inventory of spare parts is maintained at the factory and channel partners & local service providers located all over India.
