APOLLO Commercial Air-to-Water Heat Pumps provide large-scale hydronic heating, cooling, and domestic hot water from a single high-capacity platform. Available in 50-, 100-, 150-, and 200-ton configurations, APOLLO is engineered for commercial buildings and projects where performance, system flexibility, and dependable cold-weather operation are critical.
Designed for hotels, hospitals, office buildings, industrial facilities, campuses, multi-residential developments, and other high-load applications, APOLLO gives engineers and contractors a flexible hydronic solution that can be configured around the specific requirements of each project.
Instead of designing separate systems around boilers, chillers, and domestic hot water equipment, APOLLO provides a centralized air-to-water heat pump platform capable of serving multiple building loads.
Heating and cooling can be distributed through fan coils, air handlers, radiant systems, or other hydronic terminals, while domestic hot water can be incorporated into the overall mechanical design using the appropriate storage and heat-exchange equipment.
APOLLO combines Enhanced Vapor Injection (EVI) with full DC inverter compressor technology to provide variable-capacity operation across changing outdoor temperatures and building loads.
With operation down to -31°F (-35°C), the system is designed for commercial projects in demanding winter climates where conventional heat-pump performance can become a limiting factor.
Large commercial HVAC systems should not be selected from tonnage alone. APOLLO systems are sized and configured according to the building's heating and cooling loads, required water temperatures, domestic hot water demand, electrical service, hydronic distribution, climate, installation conditions, and redundancy requirements.
