Anti-Sweat Heaters (ASH Controllers)
OES installs ASH controllers that modulate anti-sweat heaters in refrigerated display cases, cutting energy waste.
Your Anti-Sweat Heaters Are Running When They Don’t Need To
The heating elements in commercial display case door frames run by default regardless of humidity. In low-humidity conditions, anti-sweat heaters burn energy with nothing to show for it, inflating costs and wearing down elements ahead of schedule.
OES installs ASH controllers that modulate anti-sweat heaters based on real-time humidity so they draw full energy only when condensation is at risk, backed by our incentive management process.
ASH Controller Upgrades Qualify for Utility Incentives
Anti-sweat heater controllers are a high-priority measure in utility energy efficiency programs. OES manages eligibility, approvals, and verification for every project. No paperwork. No missed steps. No funding left on the table.
How OES Installs and Manages Your ASH Controller Upgrade
Matching the right refrigeration controls to your existing heaters takes precise documentation and a clean installation.
Case-Level Heater Audit
We assess every case, documenting heater type, door configuration, and energy draw before anything is specified.
Incentive Authorization
We confirm utility eligibility and secure pre-approval before the product ships, locking in your funding.
Controller Installation
Our teams install ASH controllers in live environments, working overnight or during low-traffic hours.
Stop Paying Full Price to Run Heaters. Your Cases Don’t Always Need
Let OES confirm eligibility and manage your anti-sweat heater controller installation.
Anti-Sweat Heater Controllers Across Every Commercial Format
OES installs ASH controllers across every commercial refrigeration display case format.
Grocery Stores
Control anti-sweat heaters in dairy, beverage, and frozen aisles to cut energy waste without risking condensation.
Convenience Stores
Modulate temperature controller output in grab-and-go cases to reduce energy draw and keep display doors clear.
Gas Stations
Install ASH controllers in beverage and food cases to cut refrigerator controls overhead and lower energy costs.
Restaurants
Add humidity-responsive anti-sweat heater control to refrigerated display cases to reduce after-hours energy use.
Frequently Asked Questions
What is an anti-sweat heater, and what does an ASH controller do?
Anti-sweat heaters are electric heating elements in display case door frames that prevent condensation on glass. An ASH controller modulates output based on humidity, so heaters run at capacity only when needed.
Do anti-sweat heater controllers qualify for utility rebates?
Yes. ASH controllers are a high-priority eligible measure in many utility programs. OES manages the full incentive management process for every installation.
How much energy do ASH controllers save?
Savings vary by location and case count, but ASH controllers reduce anti-sweat heater consumption by limiting full-output runs to when conditions require it.
Does OES install ASH controllers nationwide?
Yes. We install anti-sweat heater controllers nationwide through our energy-efficient retrofit services, managing utility requirements at each location.
