Massive cooling power for your most demanding analytical instruments. The Yamato CLH series is a heavy-duty heating and cooling circulator with an externally opened bath. Contact Renetech!

The Product Description 

Heavy-Duty Thermal Control for External Instruments When your facility is operating large-scale rotary evaporators, laser systems, or complex distillation apparatuses, small thermoelectric coolers simply cannot keep up with the heat load. You need raw, mechanical refrigeration power to actively pull heat away from your instruments and prevent your assays from failing.

The Yamato CLH Series is engineered for maximum thermal endurance. As an advanced Cooling Water Circulator, it utilizes a heavy-duty mechanical refrigeration compressor paired with high-power heating elements. This allows the unit to seamlessly traverse a massive temperature range—rapidly chilling down to -15°C or heating up to +80°C. It is the ultimate all-in-one thermal management hub for demanding analytical and industrial laboratories.

Dual-Functionality: External Pumping & Open Bath What makes the CLH series incredibly versatile is its Externally Opened Circulation design.

1. External Chilling: A powerful integrated pump drives precisely regulated thermal fluid out of the unit and into the water jackets of your external analytical instruments.

2. Internal Incubation: Because the top of the stainless steel reservoir is open, technicians can simultaneously use the tank as a standard refrigerated water bath to immerse flasks, test tubes, or raw materials directly into the chilled fluid.

A 6-Model Lineup for Precise Capacity Matching Designed for continuous daily operation, we supply both the premium Japan-manufactured units and the highly cost-effective China-manufactured (''C'') configurations. All models are perfectly wired for 220V Malaysian power supplies:

• The 300 Series (Compact Precision): Features a 1.5-Liter bath capacity. The perfect footprint for individual benchtop distillation setups.

  • Models: CLH302 (Japan) | CLH312C (China)

• The 400 Series (Standard Workhorse): Upgrades to a 3.0-Liter bath capacity. This is the everyday standard for medium-throughput labs running multiple small condensers or larger external water jackets.

  • Models: CLH401 (Japan) | CLH411C (China)

• The 600 Series (High-Capacity Cooling): The heavy-hitter of the lineup. Features massive compressor power and pump flow for commercial-scale instrument cooling and demanding industrial processing.

  • Models: CLH610 (Japan) | CLH610C (China)

Intelligent Control & Failsafe Security Driving sub-zero coolants to expensive analytical instruments requires absolute precision. The CLH series features a highly accurate digital PID controller that eliminates temperature drift. Because a failure in cooling fluid can destroy external equipment, Yamato has equipped the CLH series with a robust diagnostic safety suite. This includes a dedicated empty-boiling prevention system, automatic refrigerator overload relays, and sensor abnormality alarms, ensuring your valuable benchtop instruments are protected at all times.
