Lochinvar CB 2066, CW 986, CB 986, CW 2066 manual Part Description Model

CB 2066, CW 2066, CB 986, CW 986 specifications

Lochinvar is a prominent manufacturer of high-efficiency heating solutions, renowned for its innovation in boiler and water heater technologies. Among its offerings, the Lochinvar CB 986, CB 2066, CW 2066, and CW 986 stand out for their advanced features and exceptional performance in commercial applications.

The Lochinvar CB series, including the CB 986 and CB 2066 models, are condensing boilers designed to deliver superior efficiency and reliability. They utilize a stainless-steel heat exchanger, enhancing durability while maximizing heat transfer, contributing to their ability to operate at efficiency levels exceeding 95 percent. These boilers are equipped with a modulating burner, allowing them to adjust the energy output according to demand, ensuring optimal operation while minimizing energy waste.

The CB 986 model features a compact design, making it suitable for installations with limited space. It has a maximum input of 986,000 BTU/hr, catering to large commercial heating requirements. The integrated control system provides easy management and monitoring, simplifying maintenance and enhancing system reliability. Additionally, the flue gas temperature monitoring feature contributes to the prevention of condensation damage.

Similarly, the CB 2066 model provides an even higher input capacity of 2,066,000 BTU/hr, accommodating larger spaces or multiple zone heating applications. The intelligent controls enable remote access, allowing facility managers to monitor performance from anywhere. This capability, combined with its whisper-quiet operation, makes the CB 2066 a top choice for noise-sensitive environments.

On the other hand, the CW series, featuring the CW 986 and CW 2066 models, focuses on water heating with the same commitment to high efficiency. The CW 986 provides a significant output capacity, suitable for supplying domestic hot water needs in commercial settings. Its innovative tankless design ensures a continuous supply while minimizing energy consumption.

The CW 2066 goes further with its high-input capacity, perfect for extensive facilities requiring substantial hot water delivery. Both CW models leverage advanced temperature control technology, providing users with precise control over water temperature, ensuring comfort and satisfaction.

In summary, Lochinvar's CB and CW series are engineered with state-of-the-art technologies that focus on efficiency, durability, and user-friendliness. With their robust construction and innovative features, including modulating burners and smart control systems, these models cater to a variety of heating and hot water needs in commercial environments, ensuring optimal performance while saving energy and reducing operating costs. Investing in these solutions not only enhances comfort but also supports sustainable practices in the pursuit of energy efficiency.
