Control Systems

A split refrigeration control box for small cold rooms, with a remote touch panel, wired and wireless connectivity, and full electrical protection.

Key Features

  • Cooling, defrost, fan and light outputs with alarm and clock functions
  • Split design: remote panel up to 200 m from the electrical box
  • Overload, phase loss, phase sequence and imbalance protection
  • Strong and weak current circuits separated for safety
  • Two temperature probes, one in use and one on standby
  • Bluetooth, Wi-Fi and 4G connectivity with remote alarms
  • One-touch energy mode using off-peak power and night defrost

Applications

  • Parallel compressor racks and packs
  • Cold storage and freezer rooms
  • Food processing and distribution facilities
  • Industrial refrigeration plants
  • Supermarket and logistics refrigeration

Product Overview

This is a split refrigeration control box built for small cold rooms. It handles cooling, defrost, fan and light outputs, and it also provides alarm and clock functions. The operating panel and the electrical box are separate units, so the panel can be placed where it is easy to reach while the box stays next to the compressor. The link works over a distance of up to 200 m.

Product Features

The panel shows three-phase current and voltage in real time. It protects against overload, phase loss, phase sequence faults and three-phase imbalance, and it uses inverse-time protection for the compressor. Strong and weak current circuits are kept apart for safer operation. Two room temperature probes are fitted, one in use and one on standby, so a single probe fault does not stop the room.

The panel connects by Bluetooth, Wi-Fi and 4G. Parameters can be set over Bluetooth from a phone, and fault and high-temperature alarms can be sent by app, SMS, email and other channels for round-the-clock monitoring. A one-touch energy mode uses off-peak power, runs defrost at night and adjusts the set temperature to cut energy use.

Structure

The operating panel carries a large LED display and five touch keys. The electrical box is installed close to the refrigeration unit, which shortens the power wiring and lowers material and labor cost. The panel connects back to the box and can be mounted in any convenient spot within the 200 m range.
