Islandaire EZ Series RK is a replacement for the Ice-Cap RSK unit. Our commercial duty construction with heavy gauge galvanized steel and superior components create an efficient reliable unit. This design eliminates the need for any interior or exterior renovation. Use of the existing wall sleeve-cabinet and louver saves time and money, two very important factors in today’s competitive environment! If the need does occur where the wall sleeve, cabinet, hydronic coil, and/or louver needs to be replaced, we manufacture these accessories as well.
