As a manufacturer of products that use natural gas, we support the growth of RNG and its use to reduce GHG emissions.

Cambridge Air Solutions is a partner in the vision of improving air quality and the environment – inside and out. We recognize renewable energy is an increasingly important part of a clean energy future for all. When people think of renewable energy, they think of solar, wind, and hydropower. It should be noted that Renewable Natural Gas (RNG) is also a clean source of energy. RNG is reliable and always available – unlike solar and wind which is dependent on the weather and time of day.

Our Director of Engineering Dave Binz describes how the Cambridge team approaches an industrial retrofit process, and the best way to get started getting answers about your project.

“Spec” buildings… You gotta love ‘em.

We, at Cambridge are frequently involved with heating “spec” buildings. You know how it goes: a developer puts up the shell, pours the concrete slab, heats the building to a minimum temperature the closes it up with no plans for ventilation. At some point in the future, the developer signs up a tenant and proceeds with the tenant fit-out. That is where our story begins.

The 200,000 sq. ft., 32’ high, uninsulated tilt wall building in Kansas City was erected in 2017 but was not occupied until 2019. In February 2020 our Regional Sales Manager learned from the Property Manager that the tenant was experiencing problems: condensation on the walls and the heaters were not maintaining the desired 55°F space temperature (although the design temperature was 50°F). A Cambridge Applications Engineer was asked to follow up to see if there was anything we could do to help.

Cambridge had participated in a “Building Burp Test” for a similar building in Allentown, PA. The test consisted of running the heating system continuously for 48 hours. The heaters were turned off, the building was ventilated with 1.5 air changes for one hour, and the heaters were turned back on. The indoor moisture level was reduced by 18%, based on datalogger results.

The tenant immediately implemented a similar plan to that outlined in the “Burp Test.” The process helped to dry out the building, but the heaters were still not operating as they should. The next step was to have a Cambridge’s Service Technician visit the job. He was able to get the four Cambridge heaters operating properly by replacing faulty discharge temperature sensors and setting the discharge temperatures to 160°F. The tenant was then able to maintain the desired 55°F space temperature.

Our experience is that providing ventilation significantly reduces moisture problems when buildings are closed up and the concrete slab is curing.
 

Cambridge Air Solutions is offering the two-stage ESC-Series to meet current market demands for custom cooling units in the industrial and commercial sectors. With an airflow range from 2,500 to 56,000 CFM, our evaporative cooling technology delivers a more comfortable working environment at a significant reduction in operating costs when compared to mechanical cooling.

In this animation, the technology of a ESC-Series two-stage evaporative cooling unit is showcased.

In this recorded webinar produced for Engineered Systems in the Fall of 2019, our VP of Sales and Marketing, Doug Eisenhart, discusses the three trends driving manufacturing excellence.

An industrial retrofit contractor who has used Cambridge S-Series heaters for years asked us to provide discharge ductwork. Some of the heaters were vertical stand mounts and some were horizontal stand mounts. The duct we provided was sized to fit the discharge opening of the heater for the vertical mount. For the horizontal mount, our standard downturn was basically rotated 180° and the duct was sized for the discharge opening. 

Our contractor commented that he liked the duct. However, it would be easier to work with and be more stable if it was redesigned with a broader, more square, cross section.

Cambridge decided to redesign the upturn and the ductwork to make it easier to work with in the field. The upturn and 3’, 4’ & 5’ vertical duct extensions have since been added to our standard product offering.
