Integral XT

Process thermostats

High-performance process thermostats for temperature control from -90 to 320 °C

The LAUDA Integral XT process thermostats are designed for professional temperature control in demanding applications. With a temperature range from -90 to 320 °C and power ratings from 1.5 to 25 kW, the systems provide high-performance temperature control for dynamic processes.

The Integral XT series operates according to the flow principle and uses a cold oil blanket, allowing temperature control media to be used over an extended temperature range. This design makes the thermostats suitable for dynamic temperature control tasks requiring wide operating conditions.

Dynamic temperature control with optimized flow rates

The electronically controlled, magnetically coupled pump allows the flow rate to be adjusted according to application requirements.

The pump can be optimized for:

  • Pressure-sensitive consumers
  • Applications with high hydraulic resistance

An eight-stage Vario pump provides preventive protection for pressure-sensitive consumers while maintaining performance even at very high pressure drops and low flow rates.

Fast heating and cooling performance

The Integral XT process thermostats are designed for rapid temperature changes, providing fast heating and cooling cycles.

Additional benefits include:

  • Extended temperature range
  • Longer service life of temperature control media
  • Reliable performance under demanding hydraulic conditions

Flexible integration and digital monitoring

The Integral XT features a modular interface concept designed for flexible integration into user processes. The systems are prepared for use with LAUDA.LIVE, a digital solution for remote maintenance and monitoring. This enables additional safety and reliability through digital process supervision.

User-friendly operation

The Integral XT process thermostats can be operated directly through a modern TFT display on the device. Alternatively, an optional operating unit with touch display and extended functions is available.

Frequently asked questions

LAUDA Integral XT process thermostats are high‑performance temperature control systems designed for professional laboratory and industrial applications. They cover an exceptionally wide temperature range from −90 °C to 320 °C, combining precise control, high heating and cooling performance, and advanced digital connectivity.
The Integral XT series operates from −90 °C to 320 °C with a temperature stability of ±0.05 K, making it suitable for applications requiring extremely precise thermal control across cryogenic and high‑temperature ranges.
The Integral XT uses a flow‑principle design with a cold oil blanket, which extends the usable temperature range of heat transfer liquids. This enables faster heating and cooling cycles, improved temperature dynamics, and a longer service life of the heat transfer medium.
An electronically controlled, magnetically coupled eight‑stage Vario pump allows precise flow adjustment for both pressure‑sensitive consumers and systems with high hydraulic resistance. Compared to previous models, the flow rate is up to 44 % higher, supporting efficient heat transfer in complex setups.
The Integral XT delivers heating output of up to 24 kW and cooling capacity of up to 28 kW, providing sufficient power for dynamic and energy‑intensive temperature control processes.
SmartCool is an electronically controlled refrigeration system that automatically adapts cooling capacity to actual demand. This ensures energy‑efficient operation, stable temperature control, and flexible adjustment for specific application requirements.
The built‑in bypass allows pressure relief and flow optimization directly within the unit. This enables easy adaptation to different applications without additional external accessories, improving system flexibility and safety.
Typical industries include aerospace (temperature cycling and simulation of space conditions), automotive (battery, electronics, fuel cell, and e-mobility testing), chemical & pharmaceutical (reaction control from R&D to production), biotechnology (temperature-critical bioprocesses and scale-up applications).
