Rink Pipe HeadersRink Pipe HeadersRink pipe circuits are brought into mechanical room & individually valved. Benefits are:
• No header trench in ice area• Circuits can be isolated if leaking• Easier to flush air from system• Fewer circuits allow good heat
transfer with lower flow and smaller pumps

Ice Kube Systems
Conventional Refrigeration PlantConventional Refrigeration Plant• 600-900 pounds of ozone
depleting or toxic refrigerant• Built on site with specialized
components• Designed for specific
temperature range• Open compressors, noisy• Large physical size,
typically requires outside door access
• Special ventilation needed for toxic refrigerant
25-40 hp brine circulation pumps
50-100 hp open compressors
Ice Kube Systems
Conventional Refrigeration PlantConventional Refrigeration Plant• Open compressors require
rebuild every 6-8,000 hours of runtime (every 1.5 – 3 years)
• Compressor oil must be drained regularly to stop performance degradation (waste oil must be disposed of properly, oil cost $500-$1,500 annually)
• Specialized service technicians & operators needed
Ice Kube Systems
Low Temperature Heat PumpsLow Temperature Heat Pumps• Small amount of “green”
refrigerant - R404A• “Off the shelf” components• Modular system design• Large temperature range• Durable stainless steel
construction • Small size, fits easily
through standard doorway• Easily serviced by local
refrigeration technician

Ice Kube Systems
How Low E Ceiling WorksHow Low E Ceiling Works
• Absorbs & emits more heat than a shiny surface
• Less heat emitted –less condensation
• Emits heat & cools more than shiny surface…allowing condensation to form
Ice Kube Systems
Reduced Ventilation LoadsReduced Ventilation Loads
Heat recovery ventilation system reduces heat loss significantly
Ice Kube Systems
VentilationVentilationHeat recovery ventilator exhausts air from locker rooms & washrooms… creating negative pressure in areas producing odors.
Fresh air supplied to arena. Transfer grills from arena supply air to locker rooms etc. Most areas heated by radiant floor heat
Benefit: No ductwork for dust to build up in & bacteria to grow in… less chance of disease transfer
Ice Kube Systems
Resurfacing IceResurfacing Ice
Electric or battery powered ice resurfacing equipment reduces ventilation load requirements
Snow removed from ice helps cool earth loop
