Solar Hybrid ACDC12 & Off-Grid DC48

ACDC12 Hybrid Solar Air Conditioning Cooling & Heating Augmentation

Augmenting a space heating or cooling system with solar makes perfect sense. In addition to heating or cooling a small area, it allows you to add capacity to an existing system, or reduce the load on an existing system, either or both of which can save you money and add comfort. Solar augmentation also allows offsetting of higher daytime electricity rates and reduces the amount of early evening catch-up required by the normal system. The ACDC12b hybrid solar air conditioner allows you to add comfort without adding cost, and can sharply cut your daytime heating and cooling bills. For spec sheet go to

DC48 Off-Grid Air-Conditioning Cooling & Heating

If your power source is native 48VDC (or -48VDC) as part of a telecom or off-grid solar application, HotSpot DC4812VRF all-DC air conditioners are your most efficient cooling choice. DC48 air conditioners can substantially reduce power supply/generation costs and battery requirements. An all-DC system means you get the advantage of extreme high efficiency without the need for inverters. For spec sheet go to


CX34 Ultra Efficient Chiller Technology - How It Works

CX34 chiller performance numbers seem too good to be true? We get that. It does seem almost impossible. That’s the reason we had the CX34 Officially Certified by AHRI. Up to 8 indoor units (IDUs) can be used. One Chiltrix ODU can connect to an amount of IDUs rated for up to 115% of the ODU capacity. ODU can also be used with ducted air handler, floor heating, or integrated with existing boiler or solar hydronic heating. For spec sheet go to

The 1-Ton Portable Climax VS12 Is The World's Most Efficient AC Unit

Climax manufactures the worlds first DC Inverter dual hose portable air conditioner, the most efficient portable air conditioner ever produced.  In high cost electricity markets, the Climax VS12 can pay for itself in less than one year, compared to standard portable air conditioners, by using about 50% of the normal energy for the same amount of cooling. Alternatively, it can perform twice the cooling for the same energy consumption. Or some mix of both, depending on conditions. For spec sheet go to
