Mobile asset management for HVAC components will soon be introduced in Browning’s widely used Toolbox Technician app! We are very excited to be demonstrating this new feature in booth 1021 at AHR Expo. Scheduled for availability in a Q2 update of Toolbox Technician, the new feature allows users to scan the 2D barcode or input the number on the Browning belt drive kit label and receive immediate access to product information. Registered users will be able to save the information to a personal library as a maintenance record, set push notifications for required system maintenance, and add related components, such as bearings, filters and compressors. The information will also be shareable with, and printable from, computers.
We surveyed contractors and building owners last year to find out how they are tracking assets and learned it’s a mix of paper notes, desktop data entry, or notes scrawled on the inside of access panels. Many admitted there were large gaps in their information because of the inconsistent way the data is captured, and there’s no centralized database or convenient way to set notifications for data they do have. Other asset management software requires tagging equipment first, but this asset management feature takes advantage of the Browning bar code kit labels provided to HVAC OEM’s for the last 10 years. Even if a drive kit label is unavailable, users can enter the kit number or other information into data fields in the app.
Asset tracking via the app will allow multiple users, such as building owners and contractors to access/share the information, eliminating the need to find paper notes or check rooftop units for logs stored there. The application updates are in beta testing, and the update is expected to be released in late spring of 2014.
The Toolbox Technician is an award winning mobile app for iOS or Android devices. You can access all of Browning’s free mobile apps here or through iTunes or Android websites.
We are very excited to introduce EPDM’s heat-resistance and durability advantages to all Browning raw-edge V-Belts, bringing an expanded temperature rating of -60° to 250°F to some of the most commonly used v-belt cross sections in the HVAC industry: AX, BX, CX, 3VX, 5VX and 8VX Gripnotch belts. The EPDM formulated belts have a 110-degree higher heat tolerance than industry-standard polychloroprene belts, making them ideal for rooftop blower units, commercial kitchens or industrial process exhaust systems.
These belts will set a new standard for the industry. Many technicians fail to account for the fact that a belt may reach 110-115°F while simply running in the sheaves at 72°F ambient temperature. If this heat is concentrated under a solid metal guard and the ambient temperature rises, it does not take long to approach the 140°F limit for common polychloroprene belts. On a rooftop in summer, even in northern climates, a v-belt drive can easily reach this critical temperature.
Browning’s EPDM formulation gives a 79% wider temperature window than polychloroprene belts. We originally introduced a limited offering of EPDM belts and due to popularity expanded the offering to all notched belts, further developing the temperature range to 250°F. This heat rating will be valuable in all applications and industries, but particularly in warmer climates.
EPDM (ethylene propylene diene monomer) is a synthetic rubber compound formulated for superior strength, flexibility and resistance to heat, decay, ozone, oxidation and humidity. For more information visit Emerson Power Transmission.
Belt Dressing: Squealing V-Belts are commonly the result of belt slippage and are the audible indicator for service technicians that something in the drive needs to be corrected to maintain proper belt tension. Using a “Belt Dressing” is treating the symptom (noise) not the disease (slippage).
Belt dressings not only camouflage the disease, they can actually have an adverse effect. Many of these products are made from petroleum derivatives, which can cause degradation of the belt construction and belt swelling when the drive has prolonged or excessive exposure. In addition, these products can be highly flammable.
Belt Slippage: Belt slippage is commonly caused by improper belt tension, worn sheaves, alignment, drive contaminants such as grease or dirt or multi-groove drives having belts produced by varying manufacturers. To diagnose a squealing V-Belt, inspect sheaves for wear. The use of a Browning groove gauge will enable you to verify that sheaves have less than 1/32” wear. Wear greater than 1/32” results in the belt not maximizing torque transition, resulting in belt slippage.

It’s the time of year again. We are headed to AHR Expo in New York City January 21-23 at the Javits Center. If you are planning to attend, we hope you’ll stop by to visit Emerson Industrial Automation in booth 1021!
This year in the booth we will introduce an expanded offering of Browning® EPDM v-belts, including new heat-resistance and durability advantages. We will also be offering a sneak peek at our Asset Management mobile app feature, which helps contractors and building owners better track HVAC belt drives and related component assets.
There are also several exciting activities happening in the booth, including seminars and giveaways. Come for one or ALL of these events! Here’s the rundown:
- Booth Seminars: Seminars highlighting HVAC OEM trends, tips for increasing belt drive and mounted bearing performance and techniques for realizing significant energy gains will occur in the booth at 11:15AM and 2:15PM daily.
- 53” Tool Chest Giveaway: Stop by the booth to enter for a chance to win a 53” tool chest. Giveaway participants must be present at the “See the Green” event to win.
- “See the Green” Event: We’ll be giving away our 53” tool chest in the booth during a #SeeTheGreen event at 1:30 PM on Wednesday, January 22nd.
We’re excited to see you all in the Big Apple. Don’t forget to look for Emerson Industrial Automation in booth 1021!
When using a sheave with more than one groove, it is critical that the v-belts be the same length so they share the transmitted load. “Belt Matching” is a term used to define v-belts of equal length. If belts are not the same length and specification, the shortest belt carries the load as it tensions in the sheave first, and the remaining belts are simply going along for the ride. Length can vary widely among manufactures.
For example, a “non-matched” B38 wrapped v-belt has a published tolerance from The Rubber Manufacturers Association (RMA) of +0.7 0 – 0.7. or 45/64 of an inch (RMA engineering standard IP-20). This means each belt can vary as much as 1.4 inches and still be called a B38. Manufacturers make v-belts within RMA tolerances, but each makes them slightly different based on their manufacturing process. For this reason, a drive should never be installed with v-belts from different manufactures. The “matched” tolerance published by the RMA is significantly closer at 0.15 or only 1/64 of an inch variation.
The downside to not having a set of v-belts within matched RMA tolerance limits is:
- Belts cannot work together as a team and belts can fail prematurely
- Transmitting maximum HP is compromised
- V-belts and sheave grooves will wear unevenly
- Belt whip & vibration is increased
