Ice storage tank KASTEL ST SD 500

An ice storage tank keeps bulk ice at a stable low temperature until it is needed for service, preventing clumping and waste. The tank does not produce ice; it receives it from an ice machine and holds it in an insulated chamber. High-density polyurethane foam between the inner and outer walls slows heat transfer, so the ice stays loose and usable for hours without refreezing into a solid block. A closing panel on top reduces exposure to room air, cutting humidity and further preserving the ice quality.

The operator loads the tank by transferring ice from a compatible Kastel ice machine into the top opening. Once the tank is filled, the closing panel is secured to seal the chamber. Ice is dispensed through a robust plastic door at the front, designed to withstand frequent opening and closing in a busy kitchen. No power is required; the insulation alone maintains the temperature.

The ST SD 500 is built entirely of stainless steel, chosen for its resistance to corrosion and ease of cleaning in a food-service environment. The outer shell and inner liner are both stainless steel, with the polyurethane foam core providing the insulation. The plastic door is mounted on sturdy hinges and can be opened with one hand, allowing quick access to the ice.

Controls are minimal: the closing panel is manually secured, and the door is opened by hand. The absence of electrical components simplifies maintenance and reduces the risk of failure in a high-moisture area.

A capacity of 550 kg means the tank can hold over half a tonne of ice, reducing the frequency of refills during peak service. The weight of 142 kg indicates the unit is heavy enough to remain stable on the floor but light enough to be moved with a pallet truck or trolley. The footprint of 1220 mm by 1128 mm requires a dedicated space in the kitchen, typically near the ice machine and the point of use to minimise handling.

Cleaning involves wiping down the stainless steel surfaces with a damp cloth and mild detergent, then drying to prevent water spots. The plastic door can be removed for thorough cleaning if needed. The insulation foam is sealed inside the walls and does not require maintenance.

The ST SD 500 is a single model with no variants. It is designed to fit a range of Kastel ice machines: KP 165, KP 300, SP 140, SP 280, KS 300, KS 600, KQ 150, KQ 250, KQ 320, KQ 400, KQ 450, KFE 250, KFE 600 and KFE 1000.

This tank is listed in the storage and refrigeration section of the professional catering equipment catalogue.
