Rubber Gate Seal for Water Filtration System Lasts Longer, Resists Disinfection, Adds Business Value

Water Filtration Case StudyWhen a manufacturer of water filtration systems needed a rubber gate seal that would last longer and resist ultraviolet (UV) light, Elasto Proxy provided a value-added solution. This custom gasket doesn’t just resist exposure to water, contact with metal and concrete, and disinfection with UV light. The gate seal also supports ease-of-installation and is ready to ship from Elasto Proxy’s warehouse in Newmarket, Ontario.

The 60-durometer EPDM lip seal (J-seal) that Elasto Proxy provides attaches to the bottom of a metal gate used in water treatment facilities. This rubber seal is also compressed against hard concrete floors and exposed to a range of temperatures. UV disinfection kills waterborne microbes that can make people sick, but ultraviolet light can also degrade rubber materials. Without reliable sealing and strong bonding, gaskets like this can’t meet business or technical requirements.

To provide a complete sealing solution, Elasto Proxy leveraged its expertise in seal design, material selection, custom fabrication, warehousing, and logistics. (more…)

Data Center Cooling Systems: HVAC Seals, Gaskets, and Insulation

Data Center Cooling SystemsData center cooling systems need to maintain temperatures that support the continuous and reliable performance of information technology equipment (ITE) such as blade servers, networking switches, and routers. If heat isn’t removed from the vicinity of sensitive ITE components, overheating can occur. If servers get too hot, onboard logic will turn-off computers to avoid damage. This protects data center assets, but results in downtime and loss of efficiency.

Data center servers can run at temperatures that aren’t high enough to trigger a shut-off, but doing so can reduce equipment life. Humidity levels and airborne contamination can impede performance, too. For data center owners, developers, and operators, the high cost of cooling is especially problematic. As Pacific Gas & Electric explains in its Data Center Best Practices Guide, data centers can consume 100 to 200 times as much electricity as standard office spaces. (more…)

HVAC Maintenance and Replacement Parts: Custom Seals, Gaskets, and Insulation

HVAC MaintenanceHVAC maintenance, repair, and overhaul (MRO) organizations need replacement parts for air handling units, air conditioners, boilers, chillers, heat pumps, furnaces, humidifiers, dehumidifiers, and other types of HVAC equipment. HVAC MROs also need to source these replacement parts in low-to-medium volume quantities that meet requirements for cost and quality.

HVAC original equipment manufacturers (OEMs) can supply rubber seals, gaskets, and insulation, but at higher prices and in greater minimum order quantities (MOQs) than some HVAC MROs want to pay. HVAC aftermarket parts are available, but commodity items aren’t the right choice when a custom sealing and insulation solution is required.

Elasto Proxy supplies custom HVAC seals, gaskets, and insulation in low-to-medium volumes. HVAC MROs like our pricing, but they also appreciate our value-added manufacturing. In addition to custom fabrication, we offer design assistance and help with material selection. If you don’t have a drawing of the HVAC component that you need to replace, just send us a sample and we’ll create a CAD file. Elasto Proxy can recommend the right rubber and the most cost-effective MOQ, too. (more…)

Skylight Seals and Load Requirements

Skylight SealsSkylight seals from Elasto Proxy can meet requirements for dead loads, live loads, local maintenance loads, and wind compression loads.

Skylights are windows that are installed in a building’s roof or ceiling. They admit natural light, support passive solar heating, and provide a visual connection to the outdoor environment. Skylights feature large spans of glass, but there’s more to these windows than meets the eye. Glass loads can be heavy, and wind loads can add weight and pressure to skylight panels. If heavy loads cause a skylight to collapse, people can get hurt. Serious damage to a building’s interior can result, too. (more…)

Rubber Door Seals for Walk-In Bathtubs

Walk-in BathtubsWalk-in bathtubs allow people with limited mobility to bathe themselves safely and independently. Typically, they’re used in hospitals, healthcare settings, retirement communities, and assisted living facilities. Unlike a traditional bathtub, a walk-in bathtub has a door on the front or side of the unit. This allows users to enter and exit the tub without having to lift their legs over the side. This reduces the chance of slip-and-fall injuries, and also supports wheelchair accessibility.

Walk-in bathtubs feature various door designs and come with various capabilities. Hydrotherapy options include whirlpools and adjustable bubble jets. Units with adjustable shower heads, integral handrails, LED lighting, and inside-the-tub seating are also available. Many walk-in bathtubs now include fast-draining capabilities so that users don’t need to remain in the unit for long periods of time while the bathtub empties. Product features vary, but all walk-in bathtubs need reliable rubber door seals. (more…)

Sound Transmission Class (STC) and Acoustic Insulation

sound transmission classSound transmission class (STC) describes the ability of a product or material to stop the transmission of airborne sound. Since the 1960s, STC ratings have been used to describe the acoustical properties of ceilings, walls, floors, and doors. Today, STC values are provided for acoustic insulation made from a single material, and for multi-layer composites that are sandwiched together. Higher STC numbers are generally better, but there are exceptions to this rule – and other factors to consider as well.

In this article from Elasto Proxy, you’ll learn what STC is and how it’s measured. For starters, we’ll cover some basic concepts about sound, vibrations that travel through the air or another medium (such as a wall) and can be heard by the human ear. Along the way, it’s important to remember that sound can also be reflected inward (such as within a metal enclosure) and cause vibrations. So while preventing the transmission of unwanted sound (noise) is important, you may face other design challenges, too. (more…)

Custom Weather Stripping for Doors and Windows

custom weather strippingCustom weather stripping from Elasto Proxy can meet the challenges of static or dynamic sealing in hot or cold weather conditions.

Here in the northern hemisphere, the days are becoming colder. In Canada, where Elasto Proxy is headquartered, the snows will arrive long before December 21, the first day of winter. At offices and factories across North America, doors and windows that let warm air out and cold air in mean higher heating costs. Leaky door and windows can also make occupants less comfortable and workers less productive.

Standard weather stripping can help, but what if your sealing and insulation application requires a specialized solution? After all, off-the-shelf rubber products aren’t designed and manufactured with your specific needs in mind. For a custom sealing solution you can count on, choose weather stripping from Elasto Proxy. All weather stripping isn’t the same, and selecting a custom-fabricated rubber product can save you time and money in the end. (more…)

Silicone Hatch Seals Resist Compression and Temperature

Silicone Hatch Seals | ST-375-23-SM
Silicone Sponge ST-375-23-SM

Elasto Proxy custom-fabricates silicone hatch seals for demanding applications. These specialty gaskets support superior sealing with good compression set and temperature resistance.

Gasket designers want rubber hatch seals that are as tough as the vehicles, equipment, and infrastructure that need them. If a hatch seal can’t withstand compression, it may over-compress and admit wind, water, dirt, or mud. If a hatch seal can’t withstand a wide range of temperatures and outdoor environmental conditions, seal failure can result, too. If you need hatch seals for military vehicles, mobile equipment, marine applications, or HVAC systems, there’s plenty to think about. Fortunately, help is available.

For every hatch seal design, compound selection is critical. As readers of this blog learned last March, choosing the right rubber won’t stop enemy fire, but choosing the wrong rubber can result in over-compressed hatch seals on military vehicles. That’s why although neoprene rubber offers an excellent balance of material properties, this elastomer wasn’t the best choice for the military gaskets that Elasto Proxy inspected. After examining the results of over-compression, we recommended silicone sponge rubber seals instead. Is this same elastomer right for your application, too? (more…)
