Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of oil temperature machines, it is recommended to prioritize checking key technical parameters such as heating power, temperature control accuracy, and maximum working pressure to ensure that they match the process requirements of the production line.
  • Oil temperature machines are widely used in injection molding or composite material curing scenarios. When purchasing, models that are suitable for circulation flow rate and temperature range can be selected based on specific industry needs.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information.
  • The oil temperature machine operating under high temperature conditions should pay attention to the efficiency of the cooling system. It is recommended to choose a design scheme that meets the long-term operating requirements for heat exchange area and medium compatibility.

Knowledge Base

Q

When choosing a circulating pump for an oil temperature machine, there are indeed several key selection techniques that need to be noted to ensure that the equipment can work efficiently and meet heating requirements. Here are some important selection considerations: 1. Head: Head refers to the height difference that a pump can overcome, which directly affects the flow and circulation efficiency of oil. Calculate the required head based on the height of the reaction vessel and the position of the oil temperature machine

Q

The jacket reaction kettle temperature control equipment oil temperature machine is a heating device mainly used for temperature control and heating of the reaction kettle. Its working principle is to use hot oil to circulate in the jacket reaction kettle, transferring heat energy to the reaction kettle materials, thereby achieving an increase in the temperature of the reaction kettle materials. This device has fast heating and can increase the heating rate by 20%
