Pro 1500W immersion heater: The heavyweight of sous-vide cooking for high-performance kitchens.

Thermoplongeur professionnel 1500W type Roner dans une cuisine de restaurant

This professional immersion heater is designed for demanding environments where precision must rhyme with power. Able to stabilize up to 30 liters of water, this “Roner” transforms any Gastronorm container or deep pot into a high-precision low-temperature cooking station. It is the ideal production tool for caterers and restaurateurs managing large volumes of set-up.

💡 Chef's Tip: Control Evaporation
For long cooking times (more than 4 hours) at high temperatures, evaporation is your enemy. We recommend using this immersion heater with heavy duty cooking bags and cover your bin with insulating balls or a suitable lid to maximize thermal stability and save energy.

Power and Stability for Intensive Service

1. Flash temperature rise (1500W)

Unlike domestic models, this immersion heater has a resistance of 1500W. This power reserve guarantees not only ultra-rapid heating of the bath, but above all immediate thermal recovery capacity as soon as you immerse your cold or frozen bags in the water.

2. XXL Capacity and Homogeneous Flow

Its high-performance brewing pump (8L/min) ensures constant water circulation, eliminating any cold spots, even when your 30 liter tank is loaded to the maximum. This stability of 0.1°C is the guarantee of identical cooking, whether you prepare 5 or 50 portions simultaneously.

3. Stainless steel ergonomics and robustness

Built to last, the device has a body made of stainless steel robust, resistant to shock and the intense heat of professional kitchens. Its touch interface is certified IPX7 (waterproof), protecting the electronics against splashes and steam, while the "dry run" safety preserves resistance in the event of a drop in the water level.
