UNIQUE CO-EX HEAT EXCHANGERS

Our CO-EX Exchanger is a COAXIAL Heat Exchanger. It performs as a Precooler and Evaporator. Our design maximizes exchanger efficiency by using Copper tubes in a coiled TUBE-IN-TUBE arrangement. Tube sizes are carefully chosen so that fluid velocities are maintained through the tubes. This promotes turbulence break up boundary and maximizes the heat transfer rate with minimum pressure drop. To further increase heat transfer efficiency, a Counter Flow pattern is used that achieves the maximum temperature difference. In addition, exchangers are fully encapsulated by PUF insulation to prevent the loss of cooling effect.

SPECIAL FEATURE OF CO-EX

• Full copper corrosion free heat exchanger.
• Non-fouling exchanger.
• Co-Axial arrangement, tends to minimize space requirement.
• Minimises power consumption
• No leakage.
• Low pressure drop.
• High efficiency

MOISTURE SEPARATOR

Cyclonic / centrifugal type moisture seperator specifically developed by GEM for condensate removal in 2KD+ Series Dryers. Designed to achieve the highest separation efficiency and maintain this efficiency from low flows to well above the rated capacity.

Efficient separation ensures that liquid condensed in the Evaporator is not carried over by the outlet air, avoids raising the outlet Dew Point. Separator is encapsulated within PUF insulation to prevent re-heating of air before separation occurs.

DEPENDABLE AUTOMATIC CONDENSATE DRAIN WITH THE FOLLOWING FEATURES

Adjustable electronic timer controlled, Pilot operated, compressed air powered, Auto drain valve. Positive discharge of even heavily contaminated condensate.

NON-CYCLIC REFRIGERATION SYSTEM

HOT GAS BY-PASS Value automatically maintains temperature across a wide range and ambient conditions without the need any adjustments. High pressure by-pass refrigerant gas is introduced after the expansion value to ensure temperature control. Direct expansion, non-cycling allows rapid response to changes in operating conditions.

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 Compressors are protected with overloads and safety trips.

ENVIRONMENTAL

GEM DRYERS are designed for low energy usage, helping to conserve the Earth's Resources and minimize pollution. Refrigerants are with low 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.
