SHENGLIN Rooftop AC: Fresh Air Unit for Philippine Factory

Date:2026-09-10

Project Overview

Manufacturing factories demand reliable fresh air HVAC systems to maintain comfortable and clean indoor working conditions for daily production. Conventional rooftop units struggle to balance fresh air intake, heating and cooling performance under the Philippines’ hot and humid tropical climate. To meet the strict environmental control requirements of a factory project in the Philippines, SHENGLIN delivered a customized fresh air type rooftop air conditioner.
This rooftop air conditioner has 21.9kW cooling capacity and 25kW heating capacity, fitted with 6kW electric heating and R410A refrigerant. It provides 3000m³/h supply air volume with 10% fresh air ratio. Fully compliant with local 220V/3Ph/60Hz power standards, it maintains steady indoor air quality and temperature, supporting safe and continuous factory production all year round.

Project Features

Factory production spaces require proper fresh air renewal together with stable temperature regulation. Ordinary HVAC units often fail to maintain balanced fresh air proportion, leading to stuffy indoor air and fluctuating temperatures that impact worker comfort and production efficiency.
SHENGLIN’s custom fresh air rooftop unit is purpose-built for tropical factory environments. With 10% controlled fresh air intake and R410A refrigerant, it delivers efficient cooling and heating, supplemented by 6kW electric heating for low-temperature periods. The unit supplies 3000m³/h airflow to evenly distribute conditioned air across the workshop.
Designed to match the Philippines’ 220V/3Ph/60Hz local grid, the rooftop unit runs stably without extra power conversion. Its integrated design keeps temperature and fresh air steady, lowering equipment failure risk and cutting long-term maintenance expenses for the factory.
 

Project Significance

This successful Philippines project validates SHENGLIN’s ability to customize fresh air rooftop air conditioners for tropical factory applications. It proves stable temperature control and air renewal performance of our rooftop units under local power and climate conditions. Drawing on rich HVAC R&D and manufacturing experience, SHENGLIN will continue improving unit performance and reliability, offering affordable, tailored rooftop HVAC solutions for industrial factories worldwide.
