The 90.64 Refrigeration Equipment Relay is a high-precision electromagnetic relay specially designed for refrigeration and freezing systems.
It functions as the electrical control core in the defrost and cooling circuit, ensuring the smooth transition between refrigeration, heating, and defrost modes.
Manufactured from high-quality copper-silver alloy contacts and flame-retardant insulation materials, this relay offers exceptional reliability, long lifespan, and consistent performance even in harsh working environments such as low-temperature cold rooms or continuous heavy-load operation.
Its compact structure, low power consumption, and easy installation make it widely applicable in commercial refrigerators, freezers, cold storage equipment, air conditioners, and heat pump systems.
| Feature | Description |
|---|---|
| Precise Switching Control | Provides reliable switching between cooling and defrost circuits to maintain stable system operation. |
| High Conductivity Contacts | Made of copper-silver alloy for low resistance, minimal energy loss, and excellent conductivity. |
| Long Service Life | Designed for more than 100,000 electrical cycles under rated load, ensuring durability and reliability. |
| Thermal Stability | Resistant to temperature fluctuations, maintaining consistent operation from -25°C to +70°C. |
