Instrument Introduction

If the heat generated by the heating components in the analytical instrument is not dissipated in time during operation, the instrument cannot work and must be cooled with cooling water. In the past, the cooling of analytical instruments often used the method of running tap water for a long time. Under normal circumstances, the consumption of tap water is based on10L/minCalculate, if working every day8In hours, the annual water consumption is approximately1440Ton, greatly wasting precious water resources and poor refrigeration effect; For areas with hard water quality, the problem of "scaling" can also affect the normal use of instruments. Therefore, the instrument cooling method commonly used at present is the circulation of cooling water.

MICHEM MCSeries Cooling Water Recirculators1995Since its launch in the market, after continuous development, it has gone from improving backward products at home and abroad to imitating * products, and then undertaking the national 15th Five Year Plan research and development project of the Ministry of Science and Technology, independent innovation. Currently, there are two series: start stop and variable frequency, with a cooling capacity of7000WThe following can all be controlled by frequency conversion.MCThe series of chilled water circulators can generate constant temperature, constant current, and constant pressure cooling water, suitable for various instruments and equipment that require water cooling and constant temperature. The product principle is advanced, the technology is becoming increasingly mature, the performance is applicable and reliable, and it enjoys a high reputation in the market.

Instrument characteristics

Ø cooling water temperature5-35℃Within the range, it can be adjusted according to requirements. By changing the frequency of the compressor, the input and output power of the refrigeration system can be automatically adjusted to achieve temperature control, energy saving, and energy-saving compared to the start stop type with the same refrigeration capacity30%above.

Ø The key components of the refrigeration system, such as compressors and circulating fans, are imported products. When the temperature is balanced, the compressor runs at low speed with minimal noise; Adopting imported circulation pump, with large circulation flow and maximum pressure reaching7.0barabove; Pressure adjustable.

Ø Micro processing chip control, high control accuracy, stable and reliable performance, andPIDCombining temperature control technology to achieve precise temperature control（±0.1℃）.

Ø Input power during compressor start-up20Within seconds, gradually increasing from small to large“soft start”This avoids the high current surge during the start-up of a fixed speed compressor and extends the lifespan of the entire machine.

Ø By changing the frequency of the compressor to achieve temperature control, the input and output power of the refrigeration system can be automatically adjusted.
