Japanese OEM Mitsubishi Heavy Industries (MHI) Thermal Systems announced the release of two updated models of central control consoles that allow management of the company’s Q-ton CO2 (R744) heat pump water heaters as well as its air conditioning units, according to a statement issued by the company.
Mitsubishi Heavy Industries Thermal Systems is a part of Mitsubishi Heavy Industries Group, which also develops and sells CO2 condensing units used in the commercial and industrial refrigeration sectors.
The new controllers, the SC-SL4-AE2 and the SC-SL4-BE2 models, will be launched in the European market this month through MHI Thermal Systems’ European subsidiary, Mitsubishi Heavy Industries Air-conditioning Europe, Ltd. (MHIAE), and will be subsequently launched in other markets.
The new models add functionality to the previous SC-SL4 series allowing connection to the Q-ton air-to-water heat pump, giving building managers “integrated, centralized control over both air conditioning and water heater units,” said MHI.
A single console can control up to 16 Q-ton units and 128 air conditioners units.
“The capability for centralized control of multiple units and energy-savings management in buildings overall will further expand sales channels for MHI’s air conditioners and commercial-use water heaters in overseas markets,” said MHI.
Q-ton is an air-to-water heat pump that “delivers extremely high energy efficiency by utilizing a natural refrigerant, along with a proprietary two-stage compressor combining rotary and scroll technologies,” said MHI on its website, adding that the unit is able to operate in ambient temperatures as low as 25°C (-13°F).
