Product Detail

Reliable Operation

● Robust Structure Design

● Anti-corrosion Solution (Optional)

● Wide Operation Range

Robust Structure Design

The unit adopts a strong structural design with high- strength galvanized steel panels and an optional aluminum alloy frame. This ensures excellent resistance to deformation and damage from external forces, providing reliable stability even under extreme weather conditions such as strong winds and heavy snow.

Anti-corrosion Solution (Optional)

Tailored for challenging environments like coastal regions and sulphide contamination areas, our corrosion resistant solutions can be customized to effectively withstand high humidity and salt mist, ensuring long-term reliability.

Wide Operation Range

The unit can operate effectively in a wide temperature range, from 5°C to 52°C in cooling mode and -10°C to 24°C
in heating mode, meeting diverse climate demands.

High Efficiency

● High EER and COP

● Efficient Heating & Cooling in One Unit

● High-efficiency Heat Exchanger

High EER and COP

Powered by advanced inverter technology, Holtop rooftop units deliver outstanding energy performance,
achieving EER values up to 12.2 and COP up to 3.7.

Efficient Heating & Cooling in One Unit

Holtop inverter rooftop units provide both cooling and heating with high efficiency, thanks to the integrated heat pump system. This eliminates the need for additional electric heating equipment, reducing upfront investment while maximizing year-round energy savings.

High-efficiency Heat Exchanger

The low-pressure-loss louvered fins, coated with hydrophilic aluminum foil, are perfectly combined with internally
threaded tubes, greatly increasing the surface area and heat transfer efficiency of heat exchanger

Ordinary tube

The smooth internal surface results in minimal disturbance to the boundary layer, lowering heat exchange efficiency.

Internal threaded copper tube

Increase the internal surface area to improve the disturbance to heat transfer boundary layer, enhancing the performance of the heat exchanger.
