Designline HBM5 Drop-In Dry Heat Bain Marie 5x 1/1 GN

The Designline HBM5 is a five-position drop-in dry heat bain marie designed for self-service countertop installations. It sits flush into a pre-formed cutout in a serving counter and provides both base heat and overhead surface heat to maintain pre-cooked food at the correct holding temperature throughout the service period. It is not a cooking appliance — its role is to protect food that has already been cooked and hold it safely for service.

The unit uses infrared quartz heat lamps mounted in an elliptical overhead gantry to provide radiant surface heat, working in combination with heated wells beneath the gastronorm containers. Individual container support collars in the well accept various GN sizes down to 150mm deep, which gives kitchen teams some flexibility in how they configure the display across a service. The modular heater element covers in the well distribute heat evenly across the base and can be lifted out for cleaning, which matters on a unit that will see daily food residue. The self-service superstructure includes curved, toughened glass sneeze screening on the customer side, keeping exposed food within hygiene requirements without obscuring it.

From an operational standpoint, the practical advantages of this unit include:

• Digital temperature display and adjustable dimmer for gantry heat, both accessible from the operator side
• Independent base and surface heat control with lockable settings to prevent interference during service
• Factory preset to hold food core temperature at 85°C, supporting food safety compliance
• 24-hour operation capability, suitable for extended service periods
• Polished steel and aluminium construction with curved profiles for a clean counter appearance

Installation requires a pre-formed cutout in the serving counter sized to the unit footprint. The HBM5 arrives with a lifting kit and a concealed control box connected via a two-metre flexible electrical conduit. It requires a hard-wired connection to a 20-amp, 230V supply — this is not a plug-in unit, so you will need an electrician involved before it goes into service. At 66kg it is a substantial piece of kit; counter structural support should be confirmed before installation. GN containers are sold separately.

This unit is well suited to carveries, hotel buffets, staff restaurants, and school or hospital catering operations where multiple hot dishes need to be held and presented simultaneously at a self-service counter. It suits medium to high-volume service where consistency of holding temperature and ease of access for customers are both priorities. For smaller counters or lower-volume service, a three- or four-position alternative may be more appropriate; for larger operations running extended or high-throughput service, it is worth discussing whether a heavier-duty configuration would serve better.

If you have questions about counter cutout requirements, electrical supply arrangements, or whether this unit fits your service setup, the team is happy to talk it through before you order.
