The Product Description 

Dynamic, Compressor-Free Thermal Control When testing advanced materials, managing small-scale bioreactors, or regulating the water jackets on analytical instruments, your laboratory often needs to cycle through both cooling and heating phases. Utilizing a standard mechanical chiller means dealing with loud compressors, heavy vibrations, and environmentally hazardous CFC refrigerants—and it still won't handle your heating protocols.

The Yamato CTW Series completely revolutionizes external thermal management. Utilizing advanced solid-state Peltier Thermoelectric Technology, it eliminates the mechanical compressor entirely. By simply reversing the electrical current, the CTW series can instantly switch from extracting heat (cooling down to -10°C) to generating heat (warming up to +70°C). The result is a highly dynamic, ultra-compact, and whisper-quiet circulator that operates with zero mechanical vibration.

An 8-Model Lineup for Your Exact Specifications Manufactured to strict Japanese engineering standards, the CTW series is designed for Externally Opened Circulation, meaning it pumps precisely regulated thermal fluid directly into your external closed-loop systems. We supply multiple configurations to match both your heating/cooling load and your electrical grid (115V or 220V via included step-down transformer):

• The 400 Series (CTW402 / CTW412 & ''S'' Variants): The ultra-compact standard. Provides up to 147W (126 kcal/h) of cooling capacity. Perfect for routing precise thermal fluid to single-instrument setups or small benchtop micro-reactors.

• The 800 Series (CTW802 / CTW812 & ''S'' Variants): The expanded-capacity thermoelectric unit. Delivers nearly double the thermal power with up to 291W (250 kcal/h) of cooling capacity. Designed to maintain strict temperatures across larger external jackets or dual-instrument setups.

• (Note: The specialized ''S'' variants feature upgraded pump systems designed to maintain consistent flow rates against higher external back-pressures).

Intelligent PID Control & Uncompromising Safety To manage the rapid transition between heating and cooling, the CTW series is equipped with a highly intelligent digital PID controller. Your Lab Manager can lock in strict target temperatures, and the solid-state Peltier system will hold it flawlessly without the frustrating temperature fluctuations caused by standard compressor cycling. Furthermore, the unit is fully equipped with an integrated safety suite, including self-diagnostic sensors and flow-rate alarms, ensuring your expensive external instruments are protected at all times.
