When the material in the reaction vessel has just completed low-temperature esterification at -10 ℃ and needs to be rapidly heated to 180 ℃ for high-temperature polymerization, the efficiency of traditional single function temperature control equipment may be greatly reduced. Due to the independent operation of the heating and cooling systems, there is a gap between the connections that causes process faults and affects efficiency during switching.

The high and low temperature integrated machine, with its three core advantages of "wide coverage, seamless connection, and precise controllability", has become an ideal partner for reaction vessels.

1. Full temperature coverage, say goodbye to equipment stacking
The high and low temperature integrated machine covers an ultra wide temperature range of -80 ℃ to 250 ℃, suitable for 50-5000L enamel, stainless steel, and Hastelloy reaction vessels. Whether it is low-temperature refrigeration of pharmaceutical intermediates (-40 ℃) or high-temperature synthesis of polymer materials (200 ℃), the entire process temperature control can be completed without replacing equipment, reducing equipment space by 60%.
2. Program seamless switching, zero gap in process connection
Equipped with a PLC intelligent control system, it supports preset multi segment temperature curves. The high and low temperature integrated machine dynamically allocates cooling/heating power through dual PID algorithm, effectively reducing temperature fluctuations caused by traditional switching.
3. Linear temperature control technology upgrades product quality
The temperature rise and fall rate control function makes the high and low temperature integrated machine widely popular in high-precision temperature control scenarios such as the chemical and pharmaceutical industries, effectively suppressing local reaction overheating and side reactions.
4. Chemical grade safety protection, stable and worry free production
Intelligent interlocking protection: for over temperature, leakage, and abnormal pressure reactions, combined with a closed circulation system, the medium does not evaporate or oxidize, and supports continuous operation for 7 × 24 hours.
The high and low temperature integrated machine has been widely used in the production of pesticides, pharmaceutical intermediates, new energy materials, various catalysts and other fields. It supports customization according to process requirements, can accurately match production scenarios, improve efficiency and reduce overall costs.
