AnyTemp® Technology

Atera’s patented AnyTemp® System is the first and only to provide a Cold, Cool, Tepid, Warm or Hot aquatic experience, indoors or outdoors, in any climate. Personalized fun, health and wellness can finally be enjoyed at home, 365 days a year, with a water temperature range between 62°F and 104°F. Daily outdoor hydrotherapy, exercise, training and swimming in perfect temperature water is finally a four season reality and no longer just a seasonal possibility! Even in Phoenix, Arizona, when it’s 115°F with 85% humidity your AnyTemp® Spa and AnyTemp® Swim Spa can be maintained at a cool, refreshing 85°F. Amazing, but true!Temperature Control

*A low setting of 56°F is also available for athletic trainers and therapists.

Economical Chilling and Heating

The AnyTemp® System works just like the HVAC
system in your home! Set it, forget it and enjoy!

AnyTemp® Chiller

Atera’s proprietary, self-contained (within the interior of the spa's monolithic structure), energy efficient, electric 6,000 Btu water chiller cools the water approximately 3°F per hour. There is no plumbing to assemble and no connection to a water source necessary.

Atera PenguinThis closed refrigeration system (much like refrigerators or freezers) won’t leak refrigerant from rubber O-rings or rubber hoses like automobile air conditioners as these weak points have all been designed out of the system. When is the last time you had to re-charge your refrigerator? Likely never! The water chiller is charged with common R134 refrigerant. If for some reason the chiller ever needs re-charging, all HVAC service technicians can easily and quickly do so. Custom sliding mounting brackets provide easy access and quick removal without disconnecting plumbing lines or electrical connections while alleviating the need to drain your spa.

All Atera AnyTemp® Spas and AnyTemp® Swim Spas will maintain a Cold, Cool or Tepid water temperature with a minimum 30°F average outdoor ambient air to water temperature variance. Even during the scorching 115°F heat and 90% humidity of the summer you’ll be enjoying a fun, refreshingly cool massage, exercise session, or swim. When you place your spa or swim spa under full or partial shade, a greater air to water variance can be obtained.

IMPORTANT NOTE: All other hot tub spas and swim spas are always heating themselves, even with the heater off as a result of kinetic energy generated by the friction of water as it goes through the pumps. All pumps generate heat that is then transferred into the water, most commonly referred to as “heat creep.” Don’t be fooled! If any pump is running, at any time of the day or night, the water in your hot tub spa or swim spa is still being heated, even when you don’t want to be heating the water!

AnyTemp® Heater

Atera Spas in Winter timeAn energy efficient 4.3 KW electric hot tub spa water heater also increases the water temperature
approximately 3°F per hour.

ThermostatSimple Set™ Controls: Your spa temperature is controlled by a proprietary control panel located on the top rail of your spa. Set it and forget it, just like the thermostat in your home. Your Atera AnyTemp® Spa or Swim Spa will be your perfect temperature, ready when you are, every minute of every day, year round.
