WATER CHILLERS - COOLING SOLUTIONS

Importance of the Topic

Precise thermal management is critical in modern analytical laboratories where instruments such as ICP, XRF, and laser systems demand stable and reliable cooling to ensure accuracy and longevity. Recirculating water chillers offer a cost-effective and environmentally friendly solution to maintain consistent temperatures under heavy load and harsh conditions.

Objectives and Overview

This document introduces LabTech’s line of recirculating water chillers designed to:

• Minimize tap water consumption and laboratory operating costs
• Deliver tight temperature stability via advanced control algorithms
• Comply with green laboratory regulations using CFC-free refrigerants
• Provide tailored cooling capacity for a variety of analytical, medical, and industrial applications

Methodology and Instrumentation

LabTech chillers integrate:

• Hot gas bypass technology to eliminate inefficient on/off compressor cycling
• P.I.D. temperature control for precise proportional–integral–derivative regulation
• Magnetic drive pumps and board‐type heat exchangers for reliable fluid circulation
• Touch-screen panels for monitoring pressure, temperature, and flow
• Eco-friendly refrigeration systems compliant with international “Green Lab” standards

Main Results and Discussion

Performance data across models (500–9000 W cooling capacity) demonstrate:

• Temperature stability as tight as ±0.1 °C over ranges from –20 °C to +35 °C
• Efficient pump flows up to 13 L/min at 60 psi, driven by pumps with power ratings from 25 to 250 W
• Reduced water consumption and lower laboratory utility costs through recirculation
• Quiet operation and minimal vibration ensured by optimized mechanical design

The robust construction and strict quality control guarantee continuous 24/7 performance, even in demanding lab environments.
