Johnson Controls’ YMAA chillers and YMPA heat pumps ramp up the competition in the entry-level chiller segment


The high price tag of even entry-level chillers has made this market segment very competitive. Johnson Controls’ Amichi Series of Chillers and Heat Pumps, introduced to the South African market just six months ago, offers a high value option, featuring a technology stack and performance that is hard to beat.

YMAA chillers by Johnson Controls offer a high value option

With capacities of 45kW up to 260kW it’s a great fit for the local mid capacity segment. More importantly, in terms of immediate capital cost concerns and long-term value, it marries the price benefit of a scroll chiller with the increased control a direct current (DC) inverter for better performance through a wider operating envelope.

Some proof:

  • The YORK Amichi Series Air Cooled Scroll DC Inverter Chillers (YMAA model) and Heat Pumps (YMPA model) offer high levels of efficiency and performance and the smallest footprint across the widest capacity range on the market.
  • The YMAA leads the scroll and screw market in part load efficiency and the YMAA/YMPA gets the best sound performance in the market with no efficiency compromise.
  • The Amichi range meets or exceeds the requirements for the Ecodesign regulations for heat pumps, comfort chillers and process chillers through an optimised combination of YORK efficiency-enhancing technologies.

Says Neil Cameron, Johnson Controls Area General Manager, and Building Efficiency – Africa, “These chillers provide an excellent fit as a solution for new builds, technology refreshes and retrofits in manufacturing and commercial facilities of up to 2000m2. They are also especially useful as dedicated solutions for data centres that demand 24×7 operation and cooling.”

“This solution competes with increasingly popular HVAC Variable Refrigeration Flow (VRF) solutions. While the VRF solutions have a lower price tag but are more complex to install, the Amichi range brings high performance beyond typical chiller efficiency levels, as well as advanced controls.”

“And there’s no compromise on efficiency – the series can maintain efficiency in a variety of conditions without kits, down to an impressive -17.8°C ambient in cooling mode, and -15°C ambient in heating mode.”

The YORK Amichi Series comprises nine packaged models of its cooling-only version, the YMAA; and nine packaged models of its reversible heat pump version, YMPA. The series uses R410A refrigerant and offers capacities from 45kW up to 260kW. Units will be held in stock by Johnson Controls with target lead times of between one and three weeks.
