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.

The Proline Kryomats Advantages
Spacious bathrooms and large bath openings – ideal for bulky samples and effective throughput
Optimal circulation and temperature distribution in the entire bath thanks to adjustable pump nozzle
Removable Command control unit with graphic LCD display – easy and intuitive operation. Quick setting changes
Automatic adjustment of the control parameters via integrated software for adaptive control – saves time-consuming calculation of control parameters
Offset control head – allows installation of optional supplementary pumps for external applications
Integrated electrically heated cover plate and bath bridge heating – avoids condensation and ice build-up
Use of innovative cooling technology – high cooling capacity and low operating temperatures with very small footprint
Updated, adjustable pump nozzle – optimum circulation and temperature distribution throughout the entire bath
Spacious baths with large bath openings – accommodates various sample shapes and sizes with efficient flow
Thread sleeves as standard on the edge of the bath – allow for the fixing of testing equipment without further conversion measures
Intelligent cooling fan control – optimum heat discharge while reducing noise emission
Internal release valve – bath drain at front of unit; No protruding release valve
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.
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.
