Product Spotlight:

iWave air purifiers are the world’s first self-cleaning, no maintenance needlepoint bi-polar ionization generator designed specifically for treating air in duct A/C systems. As the air flows past the iWave, positive and negative ions actively purify the supply air, killing mold, bacteria and viruses in the coil and living space. The ionization process also reduces allergens, smoke and static electricity, as well as controlling odors (cooking, pet, VOCs) and other particles (no more sunbeams) in the air without creating ozone or any harmful byproducts.

  • iWave-R treats the air in any brand of residential duct air conditioning systems up to 6 tons (2400 CFM) in size with NO maintenance and NO replacement parts. Designed for universal mounting, the iWave-R  is easy to install inside or outside of the duct, or can be attached magnetically near the indoor fan in the air handler.  Its patent-pending self-cleaning design includes a programmable cleaning cycle that can clean the emitter brushes every 1, 3, 5 or 10 days. The iWave-R is factory set to clean every third day which is adequate for a typical installation. iWave-R does not create “black walls” as negative-only ionizer products will do.
  • iWave-C is specially designed for light commercial systems up to 12 tons (4800 CFM) with no maintenance or replacement parts needed. iWave-C can be easily duct-mounted indoors or outdoors, depending on the application. iWave-C always works at peak performance, producing over 200 million ions/cc per polarity (400 million total ions/cc), making it superior to other market approaches. Special features include a programmable self-cleaning cycle, waterproof housing, digital display (for on-site visual monitoring) and integral alarm contact (for remote monitoring). In the event the ion emitters become damaged or wear out (after years of service), they can be replaced on the iWave-C model.
Lochinvar's New Cogeneration

Combined Heat and Power (CHP) technology—often called “cogeneration”—is a game-changer for light commercial facilities across North America. Lochinvar’s new MicroCHP solution (< 50 kW/hr) gives you the high-efficiency water heating you’d expect from Lochinvar while simultaneously generating electricity as it heats. This means once it’s installed, you will see an instant drop in your electricity bill.

Dynamic Valve = Dynamic Savings

The CircuitSolver® is a thermostatic, self-actuating balancing valve that automatically adjusts the flow through a domestic hot water recirculation system (DHWS) to maintain a specified temperature at the end of each branch.

With Configurations to satisfy any design, CircuitSolver® includes a variety of model features including an integrated union, check valve, isolation ball valves, particulate strainer, ProPress® ends, and sanitary flush capabilities.

Why Choose CircuitSolver®?

Time and costs savings
Thermostatic technology automatically and continuously modulates the valve between open and closed in response to changing water temperature, completely eliminating the need for time-consuming and expensive manual balancing procedures.

No callbacks
CircuitSolver® eliminates callbacks and unhappy tenants by consistently adjusting flow in response to temperature changes, ensuring hot water at the turn of a tap.

Completely dynamic

By relying on temperature and not flow or pressure calculations, CircuitSolver® ensures the entire system is thermally balanced to meet the design specifications without over-pumping the system.

CircuitSolver® Solution for Legionella Prevention Methods

ThermOmegaTech® offers the CircuitSolver® Union Sanitary Flush (CSUSF) Balancing Valve for thermal disinfection applications used to prevent Legionella bacteria growth. The CSUSF brings the benefits of the standard CircuitSolver® into high temperature sanitary flush applications – no manual balancing required.Using two thermal actuators to control the flow of water through a branch, the CSUSF valve allows for higher water temperatures to flow through the system during a thermal disinfection process to protect against Legionella growth.
