Leading the Industry One Pad Heater at a Time

With over 155 years of combined experience, Caliente has become the leader in the pad heater industry. We specialize in custom design in challenging and tight spaces. Because the elements are so thin, they transfer heat to the source very quickly, and doesn’t impede thermal transfer when added to a cooling system. We heat everything from electric vehicle battery heaters to military thermal targets to medical devices. The scope of our applications includes:

  • Telecom battery heaters
  • Defog/deice camera lenses
  • Emergency exit lighting
  • Lab equipment
  • Medical table warmers
  • Fast food displays
  • Ice dispenser heaters
  • Many, many more!

Essentially, if you can think it, we can heat it!

Leading Lights

Caliente manufactures all its products in house. We build heaters with polyester (rated at 105C), Kapton (rated at 180C), or silicone (rated to 200C). Our unique method of printing silver, carbon, and self-regulating PTC inks onto the various substrates allows for enormous design flexibility, including routing around holes and adding more heat in selected areas.

This method also allows our heaters to remain extremely thin (.011”) for smaller applications. These elements can range from 1” x 1” up to 24” x 72” and vary in voltage, wattage, operating temperature, and temperature controls, depending on your specifications.

Caliente’s Pad Heaters are Ahead of Their Time!

What makes Caliente the industry leader in pad heaters? Caliente’s heaters are unique because each one is custom designed to fit their client’s exact specifications. Not only do they design and manufacture everything in house, but Caliente builds in savings in both production cost and energy usage.

Caliente’s pads are extremely thin (.011”), allowing them to fit almost anywhere and deliver heat precisely where needed. These pads are also 20% more energy efficient than comparable technologies by reducing wasted heat and delivering it more quickly. They are designed to cost effectively spread heat over a wide area and eliminate the concern for hot spots and touch temperature safety issues.

Pad heaters are typically designed with a fixed resistance/wattage,but Caliente also offers PTC versions that self-regulates at a certain temperature, usually around 65C. PTC stands for Positive Temperature Coefficient, which means that as temperature increases, resistance increases. As the temperature reaches a predesignated set-point, the resistance rises and the wattage drops. These heaters do not require a thermostat because the ink functions like a self-regulating thermostat.

Many of Caliente’s pad heaters are UL recognized, including flame retardant, and are abrasion and acid resistant to protect from electrical shock, tears and burns. Pressure sensitive adhesives are commonly mounted to the back of these heaters for easier installation.

Heaters are Crucial to EV Battery Packs in Cold Temperatures!

Batteries don’t properly function in cold weather, so what does this mean for an electric vehicle? Electric vehicle batteries cannot charge, and the packs lose half of their range when temperatures drop below freezing.

Caliente has created innovative heating solutions to solve these problems. Our heaters are designed to work with the electric vehicle’s existing cooling infrastructure to push heat back into the batteries. We have created three different heater variations: pad, immersion, and radiator. Pad heaters are applied directly with the cold plate, ceramic immersion heaters are submerged in the liquid path, and radiator style heaters sit in front of the air flow systems.

The pad heaters in particular offer several advantages. At 0.011”, they are extremely thin, adding heat with minimal impact to cooling performance. The watt density can also be tailored to add more heat where there are more losses, and minimize heat in hot spots. They are also much more cost effective when compared to flow through elements on liquid based systems, removing the isolation failure mode common with this technology.

Go Farther. Even in the Cold.

Caliente is heading to the AABC Conference next month in San Francisco to present their findings on electric vehicle battery usage. We found the solution you all have been looking for!EV in Snow

Without an efficient battery heating system, electric vehicles waste valuable power staying warm enough to operate in colder temperatures. Our heaters use less electricity, which means increased driving range. We offer pad heaters for cold plate designs, PTC immersion heaters for liquid-cooled systems, PTC radiator-style elements for air-cooled designs, and custom options tailored to your needs.

Caliente Receives High Score on Performance Survey in Efforts to Obtain a GSA Schedule

Caliente is pursuing a contract under GSA to better serve its military customers. As our business grows and expands, Caliente wants to be able to meet the needs of all their clients efficiently. After being a subcontractor on GSA for a few years, we felt it was time to create our own contract. Our new restructured platform will expand our current GSA product line by presenting an updated product and price list.

In order to obtain a contract, we were required to complete a past performance evaluation survey though a third party. Open Ratings Systems distributed and collected data from our current and past customers. The results were outstanding. We received an 87, on a scale of 100, for overall performance ratings. Our highest categories included reliability, order accuracy, quality, and responsiveness. Although the responses were all positive, we will continue to keep our customers needs and wants as our first priority.

Caliente appreciates the feedback from the survey and will continue to exceed expectations, making sure we are the top performing company in the industry.

Caliente exhibiting at I/ITSEC Booth 2731 in Orlando, FL

On November 28th through December 2nd Caliente will be exhibiting their new Zero Degree reverse polarity thermal target material in Booth 2731 at I/ITSEC.booth-placement

Caliente’s new Zero Degree reverse polarity material overcomes the biggest issue with previous passive materials – that they had to be angled at 10 degrees to demonstrate an effective thermal image. Field testing at 400 meters has shown the new Caliente Zero Degree material overcomes this issue, with a much clearer and higher contrast thermal image.

The material is also thicker than previous films, allowing it to take more shots before the need to patching or replacement, providing a higher return on investment. These non-powered thermal targets are ideal for ranges where power is limited, and use a strong pressure-sensitive mounting adhesive that bonds to even wet plywood.

Whether powered or unpowered, Caliente offers the broadest and most robust line of thermal targets in the industry, including 120V, 12V, Zero Degree reverse polarity, table thermalization and specialized sniper targets.
