Description

A Subzero Temperature Controller is designed to manage low temperatures in systems like refrigeration, cryogenics, and laboratory environments.

Specifications:

• Temperature Range: -200°C to -50°C.
• Accuracy: ±0.1°C to ±0.5°C.
• Control Type: On/Off or PID.
• Input: RTD or thermocouple sensors.
• Power Supply: 110V-240V AC or DC.
• Relay Rating: 10A to 30A.
• Display: LCD/LED for real-time readings.

Applications:

• Cryogenics (biological sample storage).
• Industrial and commercial refrigeration.
• Scientific research requiring low temperatures.
• Electronics cooling.
• Pharmaceutical Storage: Ensures precise control for vaccines and temperature-sensitive drugs.

Features:

• High precision temperature control.
• Programmable settings for various needs.
• Over-temperature protection and alarms.
• Remote monitoring (on some models).
• Energy-efficient operation.
• Built-in Data Logging: Records temperature history for compliance and analysis.

These controllers provide reliable, accurate temperature regulation in environments needing precise subzero control.

Subzero Temperature Controller SZ7510 is used in heating applications when the P1 parameter is set to “1” except for SZ-7520/25/29-P. The Subzero Temperature controller is also known as Defrost controller and 7529-Pis also a defrost controller with an inbuilt power relay that can drive compressor loads directly up to 20Amps. A number of parameters are displayed alphanumerically to set up the instrument for each specific application. The Subzero Temperature controller has a measuring range of -50 C to O 99 C.
