Idle equipment corrodes faster than running equipment. A proper layup costs less than one replacement tube bundle.
Wet metal with nothing moving and no treatment pits all winter long, in the tower, the chiller and the heat exchanger.
Legionella thrives in stagnant water between 68°F and 122°F. A careless shutdown can stretch that risk across five or six months.
Scale, sludge and biofilm left in the basin and fill harden over winter and feed whatever survives into spring.
Shut down clean. Start up easy.
Our four-step fall shutdown leaves your tower protected, documented and ready for spring.
A shock biocide treatment and full flush before closing, so far fewer bacteria are left to grow over winter.
Basin, distribution deck and fill cleaned of scale, sediment and biofilm, with any damage flagged before spring.
A final water sample logged as your clean baseline and the record inspectors and insurers ask for.
A wet or dry layup chosen for your tower and climate, with off-season monitoring if water stays in the system.
Everything your cooling equipment needs before winter.
Wet layup keeps the system full with inhibitor and biocide. Dry layup drains it completely. We'll pick the one that fits your tower instead of repeating last year's routine.
Clean it now, and put the spring startup cleaning on the same order.
Protect tube bundles and plates that sit idle until spring.
The machine is already off. Descale the condenser now and stop paying for scale every hour it runs.
Cortec inhibitors protect surfaces liquid treatment can't reach, including dry layups and stored parts.
Shutdown disinfection, cleaning and the final sample are documented so your plan holds up to inspectors and insurers.
Remote monitoring and corrosion tracking keep an eye on idle systems without monthly visits.
We took it down to bare metal in a single visit without taking cooling offline, and found the hidden failure the scale had been covering up.

Questions, answered.
Wet layup or dry layup: which is better?+
It depends on your tower, your climate and how long it will sit. Wet layup keeps the system full of inhibited, biocide-treated water. Dry layup drains it completely. Each has trade-offs for corrosion and Legionella risk, and we'll recommend the right one for your equipment.
When should we shut our tower down?+
As soon as you no longer need comfort cooling, and before freezing weather. The longer an idle tower sits untreated, the more time corrosion and bacteria have to work.
Do we really need to disinfect before shutdown?+
We strongly recommend it. Most facilities only disinfect in spring, but a shock treatment and flush before closing leaves far fewer bacteria to grow over the winter, and it belongs in your Water Management Plan.
Can we book our spring startup now?+
Yes. We'll put your spring startup cleaning on the same order as your fall shutdown, so it's on the calendar before the rush.
Where do you provide service?+
Arizona, California, Colorado, Connecticut, Delaware, Idaho, Illinois, Indiana, Kansas, Kentucky, Maryland, Michigan, Minnesota, Nevada, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Texas and Wisconsin.
