Circulating Coolers ULK

The ULK series comprises high-performance, space-saving, and quiet recirculating chillers for laboratories, production facilities, and industrial applications. Customizable through a wide range of available options.

Environmentally friendly and future-orientated thanks to natural refrigerants: reduced refrigerant quantity and considerably lower GWP values (global warming potential), as well as low power consumption.

Circulating Chiller ULK Series

Characteristics

Environmentally friendly
- energy-saving fan with EC technology
- natural refrigerant with high efficiency reduces power consumption
- lower refrigerant charge quantities per device
Low operating noise
- due to particularly quiet components
- fan adjusts the speed to the demand
User-friendly
- easy filling and emptying thanks to integrated filling funnel and drain valve
- leak-free hose replacement thanks to self-sealing hose connector with quick coupling
High-quality components
- Touchscreen controller with glass surface and integrated digital display for fill level and pump status
- Brand-name components for long service life
- Hermetically sealed, air-cooled, and low-maintenance refrigeration unit
Operational safety
- Freeze and overheat protection
- Automatic pump shut-off in case of low coolant level
- Visual and audible alarms
- Clear-text error messages for quick diagnostics

Options

RS485 interface for MODBUS communication: Enables integration into control systems.
RS485 interface for ST-Bus communication: Allows easy reading and modification of values.
Voltage input for external setpoint control: Allows direct control of the temperature via external input signals.
Voltage output for actual value transmission: Transmits the current temperature values to an external system.
Potential-free contact: Enables connection to an external alarm system for enhanced safety.
Direct temperature measurement in your application: An external sensor measures the temperature directly at the process point. Automatic adjustment of the setpoint ensures particularly stable temperature control and greater process reliability compared to standard systems.
Mobile version: four castors, two lockable.
