Sustainable Refrigerants: Industrial Chiller Sustainable Refrigeration Systems
One of the First Refrigeration Technologies to Reduce Global-Warming Emissions
In the mid-1990s, Hillphoenix introduced one of the first refrigeration technologies to reduce global-warming emissions, and we continue to move sustainable refrigerants technologies from the lab to the marketplace. Our environmental improvements in alternative refrigerants and energy efficiency have helped take more than 2 billion pounds of harmful emissions out of the atmosphere since 1996. Today, Hillphoenix leads the industry with its Second Nature line of alternative refrigeration systems with over 600 installations.
Second Nature® Industrial Chiller utilizes a unique heat exchanger technology that allows engineers to design refrigeration systems with a lower refrigerant charge. The industrial chiller is comprised of multiple compact chiller modules. Each module is a standalone refrigeration system that includes a compressor, expansion valve and a multi-channel heat exchanger. The multi-channel heat exchanger works as an evaporator, condenser and sub-cooler. Each module holds a minimal amount of refrigerant and all traditional oil management system components have been eliminated.
If your company is pursuing innovative sustainability initiatives through sustainable refrigerants that lead to a smaller carbon footprint and superior cooling performance, the Second Nature Industrial Chiller is the perfect solution.
- Reduces initial refrigerant charge by 60-90% as well as required oil charge
- Reduces refrigerant leakage rates due to refrigerant pipe reduction
- Significant reduction in costs associated with refrigerant leaks
Simplified Installation and Maintenance
- Allows the use of alternative piping materials such as ABS, Victaulic and water-grade copper for installation savings
- Eliminates the use of thermal expansion valves and EPR valves
- No high pressure leak testing or evacuation required in secondary piping
- Eliminates oil return issues and costly refrigeration practices like traps and risers
- Eliminates need for leak detection in walk-ins as required by many building codes
- Extends compressor life by eliminating excessive liquid flood-back common with direct expansion systems
- Low pressure system is less prone to leaks, minimizing a major maintenance issue
- Simplified and centrally located primary system provides easier maintenance
Energy and Performance
- Can use a variety of primary refrigerants to optimize environmental and energy performance
- Evaporator close-coupled with compressor system eliminates refrigerant, suction line pressure drop and higher suction superheat typical in direct expansion systems
- Compressor unit operates with low return gas temperatures resulting in system efficiency improvement
- Eliminates inefficiencies associated with improper setting of thermostatic expansion valves
- Variable speed pumping reduces energy on pumps and compressor system during reduced load conditions
- Electronic expansion valves on chiller heat exchangers along with short liquid lines allow you to take full advantage of lower head pressures
