Johnson Controls has launched its York YMAE air-to-water inverter scroll modular heat pump in a 575-V model for use in Canadian offices, schools, health-care facilities and multi-unit residential buildings (MURBs).

The high-efficiency YMAE, already in use around the world, has been redesigned for compliance with all Canadian Registration Number (CRN) requirements for pressurized equipment in most provinces. It is engineered to deliver decarbonized heating and cooling across a wide operating range and uses the refrigerant R-454B with low global warming potential (GWP).

Building upon the York Amichi platform, the YMAE features variable-speed electronic vapour injection (EVI) scroll technology to expand heating capacities. Available in two- and four-pipe configurations, it can reportedly deliver 60 C (140 F) water in heating capacities up to 443 MBH while in heating-only mode and up to 546 MBH during simultaneous heating and cooling using recovered energy.

The YMAE is part of the OpenBlue platform for connected equipment. Up to four modules can be factory-kitted to expand capacities while maintaining a minimal footprint.
