Lauda-Brinkmann | Proline Kryomats

Extra powerful cooling thermostats for bath applications from -90 up to 200 °C

The new Proline Kryomats are floor-standing, low temperature thermostats suitable for a wide variety of applications. They never fail to impress through their compact design and high cooling capacities, especially at low temperatures. All Proline Kryomats are fitted with the Command remote control for easy and user-friendly operation.

The units are equipped with a pressure pump optimized for internal Extra powerful cooling thermostats for bath applications from -90 up to 200 °C LAUDA Proline Kryomats circulation adjustable from performance level five to eight. To prevent moisture in the atmosphere from condensing at low temperatures, bath bridge and bath edge heating are integrated into the design. Proline Kryomats stand out for having the latest technologies and an excellent price-performance ratio.

Proline Kryomats Air-cooled cooling thermostats

The air-cooled Proline Kryomats have a working temperature range from -50 and -90 up to 200 °C. The models are available with bath volumes of 30 and 40 liters. The Proline SmartCool system, with its energy saving digital cooling management, ensures that the cooling output is run in accordance with the application needs. That saves up to 75 percent of energy compared to standard cooling methods.

Two different booster pumps are available as accessories especially for external applications that require a considerable increase in volume flow/ discharge pressure.

Proline Kryomats Water-cooled cooling thermostats

In the case of the water-cooled Proline Kryomats, the process heat is disipated with the use of facility cooling water. This largely prevents unnecessary heating of the surrounding environment. As a result of this type of cooling, even higher cooling capacities are achieved than with the aircooled units. The electronic cooling water management minimizes water consumption. The enhanced booster pumps, available as accessories, are particularly recommended for external applications where increased volume flow or greater pressures are required.
