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

Explosion proof oil temperature machine is a temperature control device specially designed for use in flammable and explosive environments. The following is its detailed introduction: Working Principle By directly inserting an electric heater into the heat transfer oil for heating, and then using a high-temperature oil pump to circulate the heat transfer oil in the liquid phase, the heated heat transfer oil is transported to the heating equipment, and then returned to the electric oil furnace for heating through the outlet of the heating equipment, forming a complete circulation

Q

High temperature oil temperature machine is a device that uses electric heating to provide high temperature oil temperature. Its main components include the heating part and the control part. The heating part usually uses electric heating tubes to heat the medium to a certain temperature through the heat generated by the current. The control part includes temperature controller and time controller, which are used to control the heating time and temperature.
