Permanent rinks require engineering and craftsmanship to provide the needed longevity. The success of a rink starts with a good foundation. That is why all of our permanent installations include a Frost Shield Sub Soil Heating System in conjunction with Laser Level Fine Grading. The Frost Shield will defend against any future possibilities of underfloor heaving due to ice build-up beneath the rink surface.
Frost Shield
Frost Shield is a sub-soil heating system placed beneath the rink floor to eliminate floor heaving from frost and expansive soil materials. Frost-Shield is hydronic pipe heating system encased within a sand layer below the rink floor insulation membrane. The piping system is virtually seamless with only a few connections to the distribution header, making the system extremely reliable over its design life. A fully seamless Poly Fusion Welded system is available as well, increasing the life of your system versus PVC. An anti-freeze solution is circulated through the Frost Shield piping to maintain the soil below the rink just above freezing temperature. Heat for the solution is derived from the refrigeration system’s discharge heat.
Various Frost-Shield designs exist for new construction and retro-fit applications to handle some of the most demanding applications. For operators installing seasonal rinks today with possible expansion to year-round ice in the future, why not just install the tubing, less mechanical equipment? This arrangement reduces the investment today without limiting your operational format tomorrow. Ask your Everything Ice representative for more information about this process.
Laser Grading
In construction, the quality of the finished product is determined by the quality of the foundation. This is especially true when building ice rink floors. The fine grading process done on the lower sand layer is often regarded as the single most important factor affecting the quality and energy efficiency of the ice sheet. Having a perfectly level, compacted base on which to build a rink is even more important
The machine is driven over the sand floor while the laser control does the work, readjusting the blade every half-second. The outcome is a consistent floor that measures dead level over the entire ice sheet. This means no high spots caused by tolerant flaws, no more soft spots, and an even ice surface throughout – essentially performing like ice set on concrete flooring.
Perma Ice: Permanent Sand Base Floor
Perma Ice is used for sand base ice making systems and uses the same tough, energy efficient tubing proven with our Instant Ice product line. The system is prefabricated in 4’ wide rolls, making installation fast and easy. Each roll consists of 32 heat transfer tubes spaced every 1 ½”. Because of the size and location of the Perma Ice heat transfer tubes, the floor can be fed with an “in floor, mid rink header”, or an end feed header.
Perma Ice is ideal for new installations, placement over existing concrete floors or for repair of a failed rink floor. It has proven effective in placement directly over failed direct floor systems or indirect systems which have developed leaks from calcium chloride use. Perma Ice requires no service in a sand floor. Unlike 1” plastic tubing, Perma Ice is easy to repair should a leak occur. The following are additional advantages of Perma Ice:
- Greater heat transfer area for a 66% increase in efficiency and ice quality
- Very low pump HP requirements
- Operates with all secondary fluid solutions at low pressure drops
- Easy and fast to install, service and repair
- Close pipe spacing assures no soft spots
- Can easily be converted from a sand floor to concrete
- Installs in 4’ wide mats for less than half the installation man hours of competitive systems
Rapid Ice: Concrete Multipurpose Floor
Rapid Ice is a high performance piping system for ice making with a refrigerated concrete multipurpose rink floor. Our specialized polymer tubing works efficiently with all secondary rink fluids and is non-corrosive, providing an indefinite lifespan, unlike steel systems which corrode.
The spacing and heat transfer surface area can easily handle the highest load demands. Each system is engineered to provide uniform flow and temperature throughout all points on the skating surface.
Unique to concrete floor design, Rapid Ice is designed with the following design elements to ensure longevity, durability and peak performance.
- Depending on the heat load requirements, tubing will be spaced at either 4”, 3.5” or 3” on center to maximize heat absorption
- 1” Tubing maximizes heat transfer and flow rates, creating added efficiency
- Specialized U–Bends to eliminate leaks
- Poly Fusion welding design: this newer type of technology allows for a seamless system free from leaks and corrosion.
