RLS is the manufacturer of the original, patented, proven press-to-connect fittings for high-pressure HVAC and refrigeration applications. These are the same reliable fittings that have been in widespread use – and fully registered and listed to UL207 for pressures up to 700 PSI – since 2015.
Faster and Easier
Using an RLS-approved battery-powered tool and jaws, copper tube connections can be made in less than 10 seconds, resulting in jobs being completed up to 60% faster compared to conventional brazing. So RLS fittings help you get the job done sooner, get to the next job faster and get more jobs done. Plus, no brazing means no hauling brazing equipment and materials from jobsite to jobsite.
Safer
By eliminating the flame from the workplace, RLS press fittings create a safer work environment, removing all the dangers and precautions that come with brazing, as well as eliminating costs:
- No flammable gas
- No fire hazards
- No fire spotters
- No hot work permits
- No nitrogen purging
Reliable
The RLS patented design uses a double circular crimp that work hardens the copper to create a permanent mechanical joint that seals off the O-ring from outside air. The circular crimp also maintains the circular shape of the tube and results in a smooth ID. More than 8 million RLS fittings have been installed worldwide since 2015, so they have a proven track record of dependability. They are also backed by a 10-year limited warranty.
Full Product Line
RLS offers all the products you need to get the job done… couplings, tees, long-
radius elbows, reducers, caps and much more. Current sizes range from ¼” to 1-3/8”, with the “RLS XL” line of 1-5/8" and 2-1/8" press fittings coming later in 2020.

The BCC50 offers a 2.8-inch color screen with five illuminated touch buttons, a minimalistic design, and voice control via Amazon Alexa- or Google Assistant-enabled devices.
Users can integrate smart home apps with the BCC50 to remotely turn their thermostats on and off, change the temperature, and review current conditions and settings. Alexa or Google will recognize the device by its name, which users can customize in the Bosch Connected Control smartphone app.
They can also access intuitive functions such as app alerts, auto-on safety controls, and system air filter replacement reminders. Users can even set a schedule to ensure their Bosch Connected Control BCC50 meets specific heating and cooling needs.
The new smart device-compatible thermostat offers all the high-end bells and whistles at an affordable price point. Those features include:
- A 2.8-inch color screen with five illuminated touch buttons;
- Minimalistic, streamlined design aesthetics;
- Voice control via Amazon Alexa- or Google Assistant-enabled devices;

“Our goal with the BCC50 is to combine Bosch’s cutting-edge technology with an affordable price point,” said Joey Sung, senior project manager at Bosch Thermotechnology. “Users should not have to break the bank to enjoy comfort and quality.”
Whether through the app or device, itself, users can lock the thermostat to prohibit changes; manipulate temperature set points or modes; and monitor run times for the heating or cooling equipment, air filter, and water pad. HVAC professionals can leverage the advanced settings for better control and improved performance of the heating and cooling units and access to device logs.

Blustery days with chilling winds can cause heating problems in many facilities with high volumes of foot traffic. While the main rooms within the building may be warm from the primary heating source, many areas are left out in the cold as drafts bring the temperatures down. Vestibules, lobbies, entrance ways and hallways can all see a steady flow of people moving in and out throughout the day, opening doors and letting in chilly air.
To counteract these cold drafts, facilities should consider fan-forced wall heaters that provide continuous comfort through optimized airflow. Gentle heating sources are often not powerful enough to provide sufficient warmth in drafty areas. Fan-forced wall heaters however, push back on the infiltrating cold air, ensuring occupants feel the warmth as soon as they enter the building and until the moment they leave.
Functionality is Key
Cold air manages to find its way into facilities by any means necessary – whether it’s through vents, cracks, crevices or unsealed windows. Specialized heating units can stop these drafts before they spread throughout a building, bringing down temperatures and reducing overall heating efficiency.
Fan-forced wall heaters with an automatic delay eliminate cold drafts on start-up and discharge residual heat from the heater body during shut down. This helps attack drafts at their source while making the best use of available heat. In addition, consider fan-forced wall heaters that come with an integrated thermostat allowing for easy adjustment of room temperature to maintain a desired comfort level.
Perhaps a lobby is experiencing high foot traffic at the beginning and at the end of the workday, but have less heating requirements in the middle of the day. The adjustable thermostat allows occupants to alter the wall heater’s output based on need, ensuring no heat is wasted and temperatures remain comfortable. QMark and Berko’s commercial fan-forced wall heaters offer contemporary styles to match any room décor while ensuring adjustable warmth throughout the year.
Safety First
As with any heating unit, it is imperative to select high-quality products that offer protection against common safety risks. In terms of general design, fan-forced wall heaters come with a clear, easily accessible power on/off switch for added safety during maintenance, as well as a tamper-proof plug for the thermostat hole.
Also, look for fan-forced units with a manual reset thermal overheat protector that disconnects the power in the event of accidental blockage. This will ensure a quick repair while mitigating risk of injury. Furthermore, units that include permanently lubricated fan motors report increased longevity and lower maintenance needs, while gently distributing warmth throughout a designated area. Make sure the fan is powerful enough to offset drafts while quiet enough to eliminate unnecessary noises that may disrupt daily activities.
Key Takeaways
Every time a door opens during the cooler months, drafts blow in and bring a chilling effect into heated spaces. To neutralize the draft threats, consider installing a fan-forced wall heater to regain warmth and ensure comfortability for all occupants. Commercial fan-forced wall heaters from Berko and QMark provide strong yet safe sources of heat for the draftiest of spaces.
