Thermostatic Temperature Regulators

The Series 1140 & 1141 Temperature Regulators are designed to maintain a desired temperature for commercial and institutional heating and cooling applications. They are self-actuated and vapor pressure operated.

Series 1140 Regulators are cross ambient filled and may be used where ambient temperature exceeds the set control temperature. Series 1141 Regulators are not cross ambient filled and should not be used where ambient temperature exceeds the set control temperature.
