Taco is at the forefront of circulator innovation. Their drive to provide the most efficient, reliable pumps in the industry can be seen across their entire catalog. Taco's RMB-1 is the pinnacle of radiant heating versatility. The Radiant Mixing Block combines a variable speed injection circulator and a single stage system circulator into a single piece of equipment capable of handling up to 120,000 BTU's of radiant heating demands. It also includes a Taco Hy-Vent air elimination system and a streamlined control panel for all processes. The circulators work in tandem to mix water to the perfect temperature without wasting any heat. If you're looking for amazing radiant efficiency, it begins with an RMB-1. The variable speed circulator supports either outdoor reset control or setpoint control. If you opt for setpoint the option of adding a delta-T limit is available, for preserving a fixed temperature drop. The large LCD display on the control makes it easy to set your RMB and check system temperatures. The bronze construction of the Radiant Mixing Block makes it ideal for applications where corrosion resistance is important. A design that circumvents the need for traditional maintenance is coupled with durable components to provide you peace of mind. With Taco, your hydronic circulation is in good hands.
Replaceable Cartridge Design
All of the circulators' moving parts are contained within a removable cartridge. Servicing the RMB-1's pumps is as easy as replacing these cartridges.
Integral Flow Check
By including a removable integral flow check, Taco has improved flow performance and eliminated the need for separate in-line flow checks. All gravity flow prevention is handled by the RMB-1, streamlining your system and reducing installation costs.
Getting an RMB-1 into your radiant system is a painless process; It requires only four piping connections. Balancing valves and inconvenient tees are a thing of the past. Wiring is equally easy with the included line cord and quick, plug-in low voltage connections.
With an included boiler sensor, the RMB-1 can protect your boiler from thermal shock and condensation damage by limiting the amount of cool water return. If your RMB is in outdoor reset mode, it can provide a warm weather shutdown temperature to limit system wear and tear.
