Rack Mounted Thermoelectric Chiller HRR Series

The video opens on an industrial enclosure showing a standard 19-inch EIA equipment rack. Multiple compact HRR chiller units are slid seamlessly into the rails and secured using front-mounting brackets.

Space-Saving Rack Integration

Space-saving design. The HRR series is a high-performance temperature control device mountable directly inside a standard 19-inch rack configuration.

Core Benefit: Stacking multiple units in a centralized rack eliminates the floor or desktop footprint entirely, freeing up to 53% of physical floor space compared to standard standalone industrial chillers while facilitating easier transport.

Complete Front Access & Maintenance

Front access operation. Simple to control, service, and maintain. Without unbolting or pulling the chassis out of the server rack, a technician can easily open and service the front-facing maintenance ports.

Key Components Highlighted:

• Angled fluid fill port for spill-free fluid top-offs.

• Clear front-facing fluid level gauge.

• Fast-access particle and DI (deionized) water replacement filters.

• Front-accessible drainage port.

Efficient Refrigeration & Heaterless Heating

Heaterless Heating Architecture: The HRR series regulates temperature by pairing an air- or water-cooled refrigeration loop with a smart dual-expansion valve setup. When a temperature boost is needed, the system redirects hot, high-pressure discharge gas straight out of the compressor into the fluid circuit. This entirely eliminates the need for an electric resistance heater, optimizing energy conservation and giving the chiller eco-friendly temperature control with ±0.1°C stability.

Control Interface & Digital Monitoring

The multi-color LCD screen on the front panel allows monitoring of changing pressure, flow, and temperature values. The HRR is equipped with a standard built-in bypass valve and flow sensor.

Interface Capabilities:

Dual Display: Shows current values in white text alongside target set points in green text.

Self-Diagnostics: Continuous monitoring tracking up to 28 distinct internal fault and alarm codes.

Serial Communication: Built-in RS-232C and RS-485 communication protocols as standard for remote system starting, stopping, and data harvesting.
