High-tech components: Includes Scroll compressors, brazed stainless steel plate heat exchangers, microprocessor-based ILTC control, and HFC 407C refrigerant.
Compact design for easy installation and maintenance.
Enhanced performance with high Coefficient Of Performance (COP) compressors.
Energy savings through intelligent compressor management and reduced need for buffer tanks.

General Specifications

Cabinet made of galvanized steel with epoxy paint.
Hermetically sealed Scroll compressors with low noise and vibration.
Direct expansion evaporator with anti-freeze protection.
Air-cooled condenser coil with copper tubes and aluminum fins.
Belt-driven centrifugal fans with adjustable airflow.
Refrigerant circuit optimized for HFC 407C with pressure sensors and brazed components.
Electrical panel with power supply connections and control circuit.
Integrated hydraulic module for installation efficiency.

ILTC Control System
The ILTC system optimizes chiller operation by managing compressors and fans to reduce energy consumption. It features a user-friendly interface with menus for parameters, sensors, alarms, and operating status. The system adapts to thermal load changes and offers night-time running modes for energy savings.

Safety and Remote Management
The system includes safety devices like water flow switches and thermal relays. It supports remote management functions such as ON/OFF switching and alarm reading.

Operating Limits

Inlet water temperature: 10-30°C at start-up, 10-23°C during running.
Outlet water temperature: 5-18°C without glycol.
Air temperature: 15-46°C (standard), -7-46°C (with fan speed controller).
Correction factors for altitude and fouling are provided.

Hydraulic Circuit
Diagrams illustrate the hydraulic circuit components and configurations for basic and pack versions, including valves, sensors, and pumps.
