Displays on commercial ovens, fryers and foodservice equipment face heat, thermal shock, grease, steam and staff in gloves, and they get washed down every shift. DCL Technologies, Inc. (DCLTEK) supplies sealed, wide-temperature touch displays for commercial kitchen equipment, designed for thermal shock and tuned to keep working through steam, grease and water.

What we supply

Wide-temperature displays: industrial panels selected for the heat near ovens and fryers.
PCAP touch for kitchens: tuned for wet, greasy and gloved use through thick cover glass.
Sealed front assemblies: gasketed or bonded fronts that hold up to washdown.
Cables and harnesses: display and control cabling built to print.

What we design for

  • Heat and thermal shock from nearby cooking surfaces
  • Touch that works through steam, grease and water
  • Gloved and wet-hand touch
  • Front sealing for daily cleaning
  • Strengthened cover glass that resists impacts from pans and tools
  • Reliability testing: high/low temperature, humidity and thermal shock

Built for the kitchen line

Thermal shock. A display near an oven or fryer heats up fast every time a door opens or a cook cycle starts, then cools down slowly, over and over all day. That uneven cycling stresses the glass, the bonding and the LCD itself. We design for it with wide-temperature panels, bonding materials and adhesives chosen to handle repeated expansion and contraction, strengthened cover glass, and reliability testing that includes thermal shock.
Touch through steam. Steam leaves a film of condensation on the screen. PCAP touch is tuned to ignore that moisture so the screen doesn’t register false touches or miss real ones.
Grease and debris on the sensor. Grease films, food debris and residue build up between cleanings. Touch firmware is tuned to tell a real finger from contamination, so the screen keeps responding to wet, greasy or gloved hands.
Washdown. Gasketed or optically bonded fronts sealed to IP65, IP66 or IP67, and complete sealed assemblies when the whole unit needs the rating, so the display stands up to daily washdown and cleaning.

Questions customers ask

Will the touch screen work with wet or gloved hands?

Yes. We tune PCAP controller firmware for wet, gloved and thick-glass use. Commercial kitchen equipment is one of the applications we do this for.

How do you deal with heat inside the equipment?

We specify industrial wide-temperature panels and work with you on placement, venting and thermal design. Share your temperature profile and we’ll match the panel to it.

Can the front be sealed for washdown?

Yes. We support IP65 to IP67 front sealing with gaskets or bonded designs, and work with you on the enclosure for full-unit ratings.

Do you run reliability testing?

Our factory partners run high/low temperature operation and storage, humidity and thermal shock testing on qualified products, with reports available for customer-specific parts.

Can your displays handle thermal shock near ovens and fryers?

Yes. Kitchen displays heat quickly when doors open or cook cycles start and cool slowly afterward, many times a day. We design for that with wide-temperature panels, bonding materials and adhesives chosen for repeated expansion and contraction, strengthened cover glass, and reliability testing that includes thermal shock.

Will the touch screen work through steam and grease?

Yes. We tune PCAP touch firmware to ignore condensation from steam and the grease films and debris that build up between cleanings, so the screen keeps responding to wet, greasy or gloved hands without false touches.
