Electro Industries has always had a strong desire to internally control all aspects of product control. We are unique in that we not only internally design our products, but we also fabricate our own sheet metal parts, with a welding department, circuit board assembly, and testing.
As a company, we are continually seeking ways to improve upon and create new products to help our customers better manage their comfort and energy needs.

Whether it's reprogramming chips, troubleshooting, overall system knowledge, or customizing to meet the customer's specific needs, you'll have the answer in the palm of your hand. The Analzyer has saved many contractors from multiple trips to the job site by allowing the service technician/installer the ability to reconfigure any WarmFlo system.
          2.Product: Single Feed Bus for 3 CB's (SQ-D CB) Relay: Model 5702
          ** NOTE TO SPECIFIER ** Electro Industries has had experience working with radiant heat. We have found that in order to achieve a balanced heat using radiant, a slab thermostat is critical. Electric boiler systems require a large mass with very slow response in order to allow electric utility control interruption for off-peak rates.
 
          G.Diagnostic Tools:
          1.Product: WarmFlo Analyzer, now applicable to all TS Series: Model WF-ANZ7.
          ** NOTE TO SPECIFIER ** Our patented meter base generator transfer switch is the first of its kind. GenConnect is the first transfer switch that doesn't compromise safety in its effort to gain installation simplicity. With the simple meter base installation the GenConnect powers the complete panel - no naming individual circuits. The GenConnect is available in many different styles and amperages that can be suited for your specific needs.
