Overview

Thermaster SD-406K Heavy Duty Supermarket Glass Sliding Lid Freezer 406L

The Thermaster SD-406K is a 406-litre chest-style freezer built for demanding commercial and retail environments, featuring curved sliding glass lids that provide clear product visibility while keeping contents at a consistent -18°C to -22°C. With a Colorbond body, aluminium alloy frame, and 70mm insulation throughout, this unit is engineered to maintain temperature efficiently even in high-ambient conditions rated to Climate Class 7 (35°C/75% RH), making it well suited to busy supermarkets, convenience stores, cafés, and food service venues.

Designed as both a storage and display solution, the SD-406K is particularly popular for ice cream and frozen goods merchandising. It runs on eco-friendly R290 refrigerant, includes a heavy-duty basket for organised stock management, a lock for product security, and heavy-duty castors for easy repositioning. The analogue temperature controller keeps operation straightforward, and the manual defrost system gives operators full control over cleaning and maintenance cycles. A comprehensive warranty is available when the unit is registered within 14 days of invoice.
