Heat Pump with Electric Heat Strip (3 Phase)
These Bard wall-mount packaged units deliver all-in-one heating and cooling for light commercial applications where floor space is tight and exterior service access is preferred. Ideal for schools, modular classrooms, telecom shelters, offices, and other small to mid-size facilities, the package design streamlines installation while keeping critical components outdoors for quiet, clean indoor spaces.
Available capacities include 2, 2.5, 3, 3.5, 4, and 5 ton models, covering roughly 24,000-60,000 BTU. Systems use R-410A refrigerant and are engineered for balanced 3-phase power to support continuous duty. Electric heat strips provide auxiliary and emergency heat when outdoor temperatures drop, helping meet code requirements or specific design loads. SEER2 performance varies by model; confirm the rating needed for your region and project specifications.
Designed for licensed contractors and property managers, these wall-hung units simplify placement on modular or permanent structures with exterior wall sleeves and service panels. Typical installations use conventional heat pump thermostats and can integrate with facility controls where supported. Professional installation is required to ensure proper wall framing, condensate management, electrical sizing, and commissioning.

Frequently Asked Questions
-
What building types are Bard wall-mounted 3-phase heat pump units best suited for?
They are commonly used in schools and modular classrooms, telecom shelters, offices, guard houses, and other light commercial spaces that benefit from outdoor service access and compact footprints.
-
How do I size between 2, 2.5, 3, 3.5, 4, and 5 ton Bard wall-mount units?
Use a professional load calculation (Manual N/ACCA or equivalent). Tonnage selection depends on envelope, occupancy, ventilation, and internal loads-not just square footage.
-
Do these 3-phase heat pump packages include electric heat strips, and what kW options are typical?
Yes. Models are offered with factory-installed or selectable electric heat kits. kW options vary by unit and code requirements; your contractor will match the kit to the design load.
-
What power and wiring requirements are common for 3-phase Bard wall-mount units?
Units are available in standard commercial 3-phase configurations. Follow the nameplate for voltage, MCA/MOCP, and wire size, and install a dedicated disconnect per NEC and local code.
-
Are these R-410A packaged units suitable for outdoor wall mounting and service access?
Yes. They are designed for exterior wall installation with service access from outdoors, helping keep indoor areas quiet and uncluttered.
-
What controls or thermostats are compatible with Bard wall-mount heat pump units?
Most use standard multi-stage heat pump thermostats. Some models can interface with building automation; verify control compatibility in the unit documentation.
-
What are the ambient operating limits for heating and cooling on these heat pumps?
Operating ranges vary by model. Heating output declines in very low outdoor temperatures; optional accessories may extend cooling operation in low ambient conditions.
-
Is professional installation required for these commercial 3-phase packaged units?
Yes. Licensed HVAC and electrical professionals are required for wall preparation, mounting, electrical sizing, refrigerant commissioning checks, and code compliance.
-
How does the electric heat strip work with the heat pump in low temperatures?
The electric heat provides supplemental or emergency heat when outdoor temperatures drop or during defrost, maintaining setpoint when the heat pump alone cannot meet demand.
-
What maintenance considerations should property managers plan for?
Schedule routine filter changes, coil cleaning, and electrical checks. Keep exterior clearances open for service access and ensure condensate drains remain unobstructed.
