One valve for all purposes TGE thermostatic expansion valves

MAKING MODERN LIVING POSSIBLE

One valve for all purposes
TGE - thermostatic expansion valves

REFRIGERATION &
AIR CONDITIONING DIVISION


TGE: reliable, environmentally
-friendly and easy to use
Danfoss Refrigeration and Air Conditioning has created a brand
new thermostatic expansion valve range with fixed orifice,
tailored for OEM customers.

Especially made for large commercial air conditioning systems,
the TGE product range offers you a whole new level of performance and cost-effectiveness.

With TGE the selection of expansion valves is easy. It fits all air
conditioning applications and can be customised according to
your specific requirements.

Designed with a double diaphragm top part made of stainless
steel.
Laser-welded stainless steel power element, bulb and capillary
tube together with laser welded adjustment device reduce machining, washing and energy and guarantee you a long lifetime
of the valve as well as an environmentally-friendly solution.
