  1. Caleffi Series 551 Air Separators Brass NPT-1-1/2"

    Caleffi Series 551 Air Separators Brass NPT-1-1/2"

    Air separator with automatic ½" check valve (code 561402A) to mount expansion tank on bottom thread. Brass body. Glass reinforced nylon internal element. Max. working pressure: 150 psi. Working temperature range: 32—250°F.
    In heating and air conditioning control systems, the circulation of water containing impurities may result in rapid wear and damage to components such as pumps and control valves. It also causes blockages in heat exchangers, heating elements and pipes, resulting in lower thermal efficiency within the system. The dirt separator separates off these impurities, which are mainly made up of particles of sand and rust, collecting them in a large collection chamber, from which they can be removed even while the system is in operation. This device is capable of efficiently removing the smallest particles, with low head loss.

  7. Tjernlund MAC-4E

    Tjernlund MAC-4E

    Enables Appliances to be Interlocked in Conjunction with UC1 universal control
    The MAC4E is used in conjunction with the UC1 Universal Control to interlock up to four additional 24 VAC, 115 VAC or millivolt (Dry Contact) controlled appliances. It activates the Venter through its connections to the UC1 and in turn relies on the UC1 Fan Prover safety circuit (P1 & P2) to allow its interlocked appliances to operate. Any pre/post-purge settings on the UC1 will be defaulted to the MAC4E. Two LEDs for each appliance interlock block are provided on the MAC4E. LEDs #1, 3, 5, 7 (AMBER) shows an appliance call for heat. LEDs #2, 4, 6, 8 (GREEN) shows that the burner is approved to fire after the Venter Fan Prover safety circuit through the UC1 is completed. The MAC4E also has an LED #9 (RED) which means power is supplied to the MAC4E through the UC1.

  8. Buderus Model "N" 22, 24" x 48" Hydronic Panel Radiator

    Buderus Model "N" 22, 24" x 48" Hydronic Panel Radiator

    Model "N" 22, 24" x 48" Hydronic Panel Radiator 9200 BTU/hr, with Spring Bracket

    Buderus, the world's largest producer of cast iron boilers, manufactures high output hydronic steel panel radiators which are stocked in the U.S. Panel radiators produce an incredibly comfortable heat by providing both convected and radiant heat. Radiant heat warms objects rather than air, creating a greater sense of warmth faster and at lower room temperatures. Buderus radiators are designed to operate with individual thermostats.

    The design and styling of Buderus radiators eliminates the noise associated with other heating systems and utilize less space than baseboard. Unique Buderus styling also minimizes area where dust and dirt can collect. All these features combine to offer you a cleaner, quieter, and more comfortable source of heat. All Buderus panel radiators are supplied in powder-enameled white. If you prefer, you can paint them any color you wish. Each panel includes side panels, grill covers and flowsetter valve.

    **Note: BTU Output @ 180° F .
