Arctic Spas, a division of Blue Falls Manufacturing Ltd. (Thorsby, Alberta, Canada), produces spas that are engineered for use in cold climates.
The spas are designed with the Perimeter HeatLock™ insulation system (pictured, inset), intended to keep heat loss to a minimum and to increase energy efficiency. This includes a high-density urethane foam applied to the floor, cabinet, and spa rim underside, which results in an insulated dead air space. This is said to help electrical equipment and plumbing operate efficiently.
The design of the spa directs incidental motor heat inward, through the shell, instead of outward. Capturing this ambient heat, the company says, decreases overall heating costs.
The combination of the captured heat and the insulation system is designed to protect against freezing in sub-zero conditions. Even if power to the spa is interrupted, heat from the spa water slowly transfers to the dead air space to protect plumbing and equipment from freeze-up. The company says equipment can be protected even in temperatures as low as -40°C.
The spa hull surface is composed of high-gloss, marbled, and textured acrylics, cast with the company’s composite reinforcing process over a bonding layer and a structural layer. The wood floor is reinforced with the company’s Forever Floor™, composed of hand-rolled fiberglass composites. The floor is designed to be impervious to the damage of moisture, pests, and time, and to eliminate the need for a concrete, decking, or block foundation.
The company says its products are the first in the hot tub industry to use reflex torsion hose in every spa. This specialized pipe material is designed to fit over rigid PVC and is glued into all fittings to allow for higher water flow and help avoid fitting leaks due to hose movement. The PVC pipe material is designed to swell to absorb stress from fittings.
The company says heaters generally are the most failure-prone spa component because the heating element is typically submerged, exposing it to potential chemical imbalances and poor quality water. Arctic addressed the problem by designing the Tru-Guard heater, which is sealed using a protective Teflon-titanium-based coating that is similar to the coating used to seal commercial acid tanks. The coating inhibits mineral buildup and protects against corrosion.
The topside digital controls are designed to perform in cold conditions. They control temperature well as the programmable heat and filtration cycles. The control unit also oversees diagnostics, flow-switch failure, over-heat protection, and freeze protection. Self diagnostics allow for easy servicing.
The water filtration system starts with a pre-filter that attaches to the hose used for filling the spa. This pre-filter contains a proprietary, micron filter media designed to capture metals, suspended solids, and bacteria.
The company also developed a disposable filtering system to help eliminate filter cleaning. The Micro Pure™ Everyday Filter is said to provide the equivalent of more than 900 sq ft of pleated paper or cellulose filter media. The filter captures particles and small as 1 micron and is said to be 94-percent efficient at removing contaminants in one pass. The company says some pleated filter systems screen down to only 60 microns and are only 50-percent efficient. This high level of water cleaning efficiency is designed to do away with the use of chemical clarifiers, cartridge cleaners, and defoamers.
