Combined Thermostatic Controllers

AVTB

AVTB is self-acting temperature controller used to control the water temperature in hot water tanks, heat exchangers, oil preheaters, etc. Controller closes on rising temperature. The controller has a control valve, thermostatic actuator and handle for temperature setting. Thermostatic actuator consist of a bellows, capillary tube and sensor.

AVTQ

AVTQ is a self-acting flow-compensated temperature controller primarily for use in district heating systems with plate heat exchangers for instantaneous hot water production. It closes on rising sensor temperature. It has permanent no-load (idle) temperature setting on about 40 °C which is offset by a pilot valve using flow-compensation principle during tapping. Tapping temperature can be set individually. AVTQ prevents high temperatures in the heat exchanger when no hot water is tapped by rapidly shutting off the heat supply (e.g. hot district heating water). AVTQ can be used with most plate heat exchangers. However, the heat exchanger manufacturer should be contacted to ensure that the chosen heat exchanger has been approved for use with the AVTQ: Pressure-controlled opening/closing on start/stop tapping and infinite adjustment of operating temperature.

FJV

FJV is self-acting temperature controller used to control: return water temperature from hot water tanks in direct connected district heating systems and return water temperature in district heating systems with mixing loop. The FJV ensures that return water is cooled to required temperature before it flows back to the district heating plant. Controller closes on rising temperature. The controller has a control valve, thermostatic actuator and handle for temperature setting. Thermostatic actuator consist of a bellows only. For block and district heating systems.

IHPT

Self-acting controllers are designed to be integrated directly to heat exchanger. They are developed to control instantaneous heating of domestic hot water by means of heat exchanger. The family of products offer full flexibility of different requirements regarding control performance and idle condition (no load conditions). Innovative design enables simple, fast and reliable connection to heat exchanger and most important production of ultra compact and user friendly stations for heating of domestic hot water. The capacity of controllers fully covers the needs of domestic hot water for flats, one family houses or dwellings and can be mounted to district heating network directly, to a block of heating systems or central located boiler system in a dwelling house. The controller is connected to primary heating system as well as cold water system. To avoid risk of leaking from one media to the other the controller is equipped with double sealing.
