The bottle warmer as a process stabilizer between cleaning and filling
The automated bottle warmer from Whystler Automation is a central drying solution for bottles and jars within modern liquid bottling lines. As a specialized drying machine for the beverage industry, the bottle warmer, or preheater, is used after the cleaning process to precisely temper bottles and jars and prepare them for the next processing steps. Utilizing medium-wave infrared preheating technology, the containers are heated evenly, reducing residual moisture and reliably drying surfaces. This is a significant difference compared to systems that use hot water or steam.
Targeted heating raises the container temperature above the dew point, actively preventing condensation. At the same time, the Whystler bottle warmer reduces the risk of glass breakage during hot filling processes and improves the adhesion of labels and sleeves. Automatic temperature control ensures consistent and reproducible heating, leading to uniform results throughout the entire production run. Thanks to its modular design, the drying machine can be flexibly adapted to different line layouts, performance requirements, and container formats. Seamless integration into existing production lines in the beverage processing industry is therefore easily achievable. The result is significantly greater process stability, less waste, and consistently high product quality – even on high-speed lines.
With or without pre-head – the crucial difference explained briefly
With bottle warmer (PreHeat)
- Bottles above the dew point → no condensation
- Dry, temperate surface → optimal labeling
- Reduced temperature stresses → less glass breakage
- Consistent processes → higher line output
- Significantly less waste and downtime.
Without bottle warmer (PreHeat)
- Condensation forms on cold bottles
- Poor adhesion of labels and sleeves
- Increased risk of glass breakage during hot filling
- Unstable processes at high line velocities
- Higher committee and follow-up work
In short: The use of the Whystler bottle warmer is the most energy-efficient solution on the market and, by eliminating the need for a complex water cycle, extremely sustainable.

FAQs – Bottle warmers
When does a Whystler bottle warmer make sense in the bottling line?
A bottle warmer from Whystler Automation is particularly useful when residual moisture remains on bottles or jars after the cleaning process, or when temperature differences cause problems during filling. Typical applications include hot filling processes, labeling with high quality requirements, or high-speed lines where condensation and glass breakage must be avoided.
How is the automated bottle warmer from Whystler Automation integrated into existing production lines?
Thanks to its modular design, Whystler's automated PreHead solution can be flexibly integrated into existing production lines in the beverage industry – typically upstream of the rinser integrated into the filler. Adaptation is made to existing conveyor technology, line speed, and infeed and outfeed heights. Retrofit projects in existing systems are also easily possible. Learn more under the "Service und Retrofit." section.
What advantages does medium-wave infrared preheating technology offer compared to hot air solutions?
The widely used infrared technology heats bottles and jars precisely and directly, without heating the surrounding air. This results in efficient energy use, reduced warm-up time (a particular advantage when changing formats), and a uniform temperature distribution. Compared to hot water or steam systems, medium-wave infrared technology is more energy-efficient and reduces operating costs. Furthermore, medium-wave IR technology prevents residual moisture from forming in or on the bottle, leading to significantly improved hygiene standards.
How is consistent temperature and process quality ensured?
The bottle warmer is an automation solution from Whystler Automation that operates with automatic temperature control and zone-controlled heating. This ensures that all containers are heated evenly and reproducibly – regardless of line speed or format changes. The result is consistent processes, high hygiene standards, and consistently high product quality. And above all, fast warm-up times during format changes.
For which types of bottles and containers is the automated drying solution from Whystler Automation suitable?
The automated bottle warmer developed by Whystler is suitable for glass bottles and jars in various formats. Thanks to its flexible zone control and modular design, the system can be automatically adapted to different container sizes and production requirements, thus reducing downtime due to format changes and resulting in very fast response times and controllability (depending on customer requirements).
How economical is the use of an automated bottle warmer (ROI)?
Using a Whystler bottle warmer typically pays for itself quickly, as it reduces several cost factors simultaneously. These include less waste due to reduced glass breakage and less rework during labeling. At the same time, the energy-efficient medium-wave infrared technology ensures optimized energy use. Overall, this leads to rapid amortization and sustainably lower operating costs.
