Internal Retrofit Terminal Units

36VR Series

Designed to replace the mechanical regulators in old "system powered" terminal units in order to substantially lower the operational static pressure requirement. The air valves include a damper, flow sensor and actuator and make use of state-of-the-art controls in order to reduce operating cost.

• Custom built on a specific project basis
• Variable or constant volume pressure independent airflow control.
• 'Diamond Flow' multi-point averaging flow sensor.
• Models available to retrofit most 'brand name' terminal units.
• Pneumatic, analog electronic or digital control.
