Everest and Embraco Launch Brazil's First Inverter Water Purifier with R600a

Everest Refrigeration, celebrating its 60th anniversary this year, has partnered with Embraco on a water purifier that introduces inverter technology to the Brazilian market for the first time. The product, named Plus Inverter+, targets high-flow, noise-sensitive environments such as companies, offices, and clinics. The collaboration builds on a partnership between the two companies spanning more than 40 years.

The core of the solution is a customized sealed unit developed by Embraco, integrating a variable-speed (inverter) compressor, condenser, evaporator, filter drier, capillary tube, and R600a natural refrigerant charge. The evaporator is manufactured by Everest and assembled by Embraco into the final hermetically sealed package. This "plug-and-play" approach allows Everest to increase production capacity within its existing plant without sourcing individual components from multiple suppliers or investing in new assembly lines, while also reducing the number of SKUs on the factory floor.

A key enabler of the R600a transition is the sealed-unit architecture: because the refrigerant charge is pre-loaded and sealed, Everest no longer needs to handle refrigerant fluids during purifier assembly. Without this approach, adopting R600a would have required significant investment to adapt production infrastructure.

At the heart of the sealed unit sits the Embraco FMS inverter compressor. Its variable-speed technology lets the compressor dynamically adjust RPM to match cooling demand, eliminating the on-off cycling of conventional compressors. The FMS is one-third smaller than its predecessor, the EMI, while delivering the same cooling capacity with greater energy savings. The compressor also features automatic dual-voltage capability (110 V / 220 V), removing the need for consumers to select a voltage and improving resilience to voltage fluctuations.

Performance comparison (NBR 16236 test method)

Parameter	Conventional Plus	Plus Inverter+	Change
Energy consumption	6,450 kWh/month	1,910 kWh/month	70% lower
Weight	13 kg	9.8 kg	25% lighter
Noise level	61 dBA	50 dBA	15% quieter
Refrigerant	R134a	R600a (natural)	GWP reduced from 1,430 to 3
Cold water output	1,896 L/h	2,000 L/h	5.5% increase

Beyond the direct product gains, Embraco's accumulated experience with inverter technology across other customers and applications points to an up to 80% reduction in field failures, which the company says translates into greater product durability.

Carlos Alexandre Guimarães, Commercial Director at Everest, described the Plus Inverter+ as a significant technological advancement in the company's portfolio, noting that it addresses three strategic market trends: growing concern over energy consumption, demand for continuous-service solutions in corporate and professional environments, and the search for quieter, more durable, and sustainable equipment.
