Integral T

Process thermostats for professional external thermostating across a wide temperature range from -30 up to 150 °C

Integral T

Integral T process thermostats are particularly suited for external temperature control of reactors, mini plants and calorimeters. They provide broad temperature ranges and rapid temperature changes. The temperature of external applications can be controlled precisely with defined heating and cooling speeds. With the Integral T, internal circulation allows temperature control independently of external current resistances.

  The Integral T advantages Your benefits
  • Small active internal volume
  • Bypass valve between inlet and outlet as a standard feature
  • Rapid temperature change and effective control of exothermic reactions

  • May be adapted to various applications
  • Compact design, all devices fitted with
    castors
  • Remote control options available with use of accessory
  • Saves valuable laboratory space
  • Flexible applications
  • Mounting and sub-assembly option

Integral T Process thermostats up to 2.7 kW

Integral T process thermostats make rapid thermostating with powerful heating and cooling capacities combined with a small active internal volume possible. This minimises thermal drift and exothermic reactions are effectively controlled. Its compact construction is space-saving and makes the Integral T mobile.

The T control unit can simply be flipped open. The following interfaces are then accessible from below: connector for standby contact input, malfunction (alarm) contact output, analogue inputs and outputs, external Pt 100 and serial RS 232/RS 485 interface.

From the T 4600 units and larger, the Integral T is equipped with an additional pump allowing for more powerful circulation in the internal circuit. An adjustable bypass valve between the supply pipe and the bath of the external circuit allows for pressure reduction (e.g. in order to protect pressure-sensitive applications).

Integral T Process thermostats up to 13 kW

Integral T 7000

The more powerful T 4600 to T 10000 W Integral process thermostats have a second pump for circulation in addition to the powerful circulating pump via an internal plate-type heat exchanger and therefore provide efficient and space-saving cooling. This enables a cooling capacity of 4.6 to 13 kW at 20 °C with the smallest internal bath volume.
