Data Sheet

Hot gas bypass regulator
Types TUH, TCHE and TGHE

Capacity regulator

TUH, TCHE and TGHE capacity regulators adapt
compressor capacity to actual evaporator load
in applications operating at an evaporating
temperature of around 0°C.

TUH, TCHE and TGHE valves are typically used
in applications such as:

• Air driers

• Water chillers

Fitted in a bypass between the high and low­pressure sides of the air-drier system, TUH,
TCHE and TGHE maintain compressor suction
pressure by injecting hot gas/cool gas from the
high-pressure side.

TUH has internal pressure equalisation and
opens when pressure drops at the valve outlet.
TCHE and TGHE have external pressure
equalisation and open directly when
compressor suction pressure drops.

For all types, the bulb only serves as a reservoir
for the charge. However, it is recommended
that the bulb be mounted in a location where
temperature variation during operation is
limited.

Functions

Figure 2: TCHE, Angleway

Figure 4: TGHE 20, TGHE 40 Straightway

The valve is set to start opening at an evaporating temperature of +2°C/+36°F. The setting can be changed by
turning the setting spindle. The temperature at which the valve starts opening is increased by turning the spindle
anti-clockwise and decreased by turning the spindle clockwise.

Specically designed for hot gas applications.

All valves react only on to suction pressure variation.

The bulb serves only as a reservoir for the charge, however, it is recommended to mount it in a position where the
temperature variation during running conditions is limited (see a and b in the drawings below).

Sizing

Figure 5: Sizing example for R134a

Conditions used in calculation: tc = +40°C, Start opening te = +2°C

Correction for condensing temperature

The corrected replacement capacity can be obtained by dividing the replacement capacity with the correction
factor given below.

Table 1: Correction factor for condensing temperature

Example

Refrigerant: R134
Compressor capacity: 6 kW at +2 /+50 °C
Min. load 50%: 3 kW
Replacement capacity: 6 – 3 = 3 kW

© Danfoss | Climate Solutions | 2021.02 AI000086422949en-000401 | 5

Hot gas bypass regulator, types TUH, TCHE and TGHE

Min. evaporating temperature te: -1.0 °C
Condensing temperature tc: +50 °C
Correction factor (table): 1.2

The corrected replacement capacity thus becomes 3 kW divided by 1.2 = 2.5 kW. The TCHE 4 gives 2.7 kW at

-1.0/+40°C (....) and gives 2.5 kW at -0.8/+40°C (- -). Thus the TCHE 4 would be a suitable choice.
