HOW IT WORKS
Our technology, our model, and the results we deliver
BITZER VSD COMPRESSOR RETROFITS
The Problem: Your traditional refrigeration compressor draws 6-8x its normal current when it starts up. This "inrush current" is devastating for solar systems and drives up electricity costs year after year.
The Solution: We retrofit your existing compressor with Bitzer equipment and ABB Variable Speed Drives. The VSD provides a smooth, intelligent ramp-up — using only 2-3x running current instead of 6-8x. No massive startup surge.
The Result:
- 20-40% energy reduction — savings start immediately
- Smaller, cheaper inverter required for solar
- VSD modulates speed for continuous efficiency
- Foundation for CaaS shared-savings agreements
Who benefits? Supermarkets. Cold storage facilities. Butcheries. Restaurants with walk-in coolers. Food processors. Dairy operations. Any business with significant refrigeration or air conditioning loads.
Through our CaaS model, retrofits can be funded from verified savings — no upfront capital required.
