Project Overview

Industrial facilities requiring low-temperature process cooling demand consistent, reliable chiller performance to maintain production quality and uninterrupted operation, especially in tropical climates with persistently high ambient temperature and humidity. Standard air-cooled chillers typically suffer from degraded cooling capacity, elevated condensing pressure and unstable operation when delivering sub-zero coolant under prolonged high ambient conditions, which risks process disruption and rising operational expenditure. To meet the rigorous low-temperature cooling requirements of an industrial project in Singapore, VENTTK delivered a customized air-cooled screw type chiller.

Project Information

• Country: Singapore
• Product: Air Cooled Screw Chiller
• Application: Industrial Facilities Process Cooling
• Cooling Capacity: 117kW per unit
• Design Condition: Inlet coolant -25℃, Outlet coolant -20℃
• Refrigerant: R404A
• Supply Power: 400V/3Ph/50Hz

Project Features

Industrial process cooling operates at sustained heat loads with strict requirements on low-temperature stability, compressor reliability and freeze protection.In Singapore’s year-round hot and humid climate, off-the-shelf chillers frequently face excessive discharge pressure, capacity attenuation and higher failure rates under sustained sub-zero operating conditions, which can interrupt production workflows and drive up long-term maintenance costs.

VENTTK’s tailor-made air-cooled screw chiller is fully optimized for low-temperature industrial process conditions. Built around a heavy-duty screw compressor platform and calibrated for R404A refrigerant, the unit is engineered to deliver steady cooling performance at -20℃ supply temperature, even under elevated ambient temperatures. The air-cooled condenser is specially sized and configured for tropical environments, maintaining reasonable condensing pressure and avoiding the efficiency drops common to standard units in high-temperature climates.

The unit is highly compatible with Singapore’s local 400V/3Ph/50Hz power grid, running stably without additional power conversion devices. With optimized refrigerant circuits, built-in capacity regulation and a comprehensive protection suite, it maintains continuous rated low-temperature cooling output, effectively mitigating process fluctuation and equipment downtime risks, while reducing long-term operation and maintenance costs for the project.

Project Significance

This successful deployment in Singapore verifies VENTTK’s professional capability to customize low-temperature air-cooled screw chillers for tropical industrial scenarios, and proves the excellent ambient adaptability and operational reliability of our chiller systems under Southeast Asian high-temperature and high-humidity conditions. Leveraging mature refrigeration solution R&D and manufacturing experience, VENTTK will continue optimizing low-temperature cooling efficiency and system reliability, providing professional and cost effective chiller solutions for global industrial process cooling, manufacturing and commercial facility projects.
