Hillphoenix Launches ChargeSecure to Help Food Retailers Maintain CO2 Charge During Power Outages and Service Events

DOWNERS GROVE, Ill., June 12, 2024 /PRNewswire/ – Hillphoenix, part of Dover Food Retail and Dover (NYSE: DOV) and a pioneer in designing environmentally sustainable refrigeration systems, today announced the launch of ChargeSecure™, a charge preservation solution for CO2 refrigeration systems that offers peace of mind during power outages and service events.

Designed specifically for Hillphoenix CO2 systems, ChargeSecure minimizes downtime and offers peace of mind during power outages and service events by maintaining charge. When the power comes back on, the system can restart immediately – helping stores get back up and running faster.

“With our decades of experience in natural refrigeration systems, we designed ChargeSecure to offer a layer of security for food retailers using our CO2 systems, so they can get back to doing what they do best – serving their customers,” said Ousama Sabra, Systems Senior Product Manager at Hillphoenix.

A future-focused, environmentally friendly solution, ChargeSecure uses the existing CO2 in the system to operate instead of relying on legacy refrigerants. This technology solidifies Hillphoenix’s reputation as the leader in natural refrigerants.

“As the adoption of CO2 refrigeration systems continues to accelerate, ChargeSecure addresses the growing need for a charge preservation solution with a low GWP impact,” Sabra said.

ChargeSecure automatically kicks in when it detects a power outage and/or pressure increase beyond a predefined threshold. It maintains the CO2 pressure in the flash tank by compressing it into the gas cooler and then expanding it back into the flash tank.

Benefits of ChargeSecure include:

  • Cost Savings: Retailers can avoid the time and expense of recharging CO2, while also helping to protect perishable goods from loss.
  • Low Power Consumption: Requiring only 1.5 amps to operate, it uses 6 times less energy than conventional charge preservation units.
  • Flexible Installation: It can be mounted on the wall or floor – anywhere within 15 feet of the rack – indoors or outdoors.
  • Small Footprint: With no heat exchanger required, its compact footprint measures 12.75 inches by 18.8 inches.
  • Extended Operation: Backup battery provides prolonged periods of continuous operation.

For retrofits, ChargeSecure features easy plug-and-play integration into existing Hillphoenix CO2 racks. Hillphoenix will be offering factory-installed ChargeSecure units in new racks.
