Dynamic Cold Therapy • DCT-SV-10DO3
DCT Premier Edition 1.0 HP Cooling and Heating System with Wi-Fi App
The DCT-SV-10DO3 is the larger of the two Dynamic Cold Therapy Premier Edition systems — a combined chiller and heater with a range of 37°F to 85°F, rated for tubs up to 150 gallons, with Wi-Fi app control and built-in ozone, filtration and a strainer. The extra capacity over the 0.8 HP unit matters most in larger tubs and warmer rooms.
Wellari Expert Take
Why Consider the DCT-SV-10DO3?
Both Premier Edition systems reach the same 37°F floor, so the question is not how cold but how easily. Chiller capacity determines how quickly a tub comes down to temperature and how steadily it holds there once it arrives — and both of those get harder as water volume rises and as the surrounding air gets warmer.
Size up to the 1.0 HP when any of these apply: the tub is at the larger end of the range, it lives outdoors or in an unconditioned garage, your climate is hot, or the plunge gets used and opened several times a day. A unit with headroom cycles less and holds a tighter temperature band than one working near its limit.
Best For
- Larger tub volumes, or any Dynamic tub used heavily through the day.
- Outdoor, garage or unconditioned installations, and hot climates.
- Owners of a Dynamic Cold Therapy tub bought without a cooling system — the tubs are supplied tub-only.
- Buyers who want the tub to double as a warm soak out of season — this unit heats as well as cools.
- Setups where holding a tight, consistent temperature matters more than the purchase price of the system.
DCT-SV-10DO3 Features & Buying Details
Cooling, Heating & Water Care
- Power: 1.0 HP
- Function: Cooling and heating
- Temperature range: 37°F to 85°F
- Tub capacity: Up to 150 gallons
- Cooling rate: Approx. 1–3°F every 20 minutes, depending on ambient temperature and water volume
- Use environment: Indoor and covered outdoor rated
- Control: Wi-Fi mobile app (Tuya Smart)
- Water care: Built-in ozone, filter and strainer
- Connections: 3/4-inch inlet and outlet
37°F is the floor, not the setting. Most people plunge between the mid-40s and mid-50s. What the extra capacity buys is not a colder minimum — both units share it — but a faster pull-down and a steadier hold at whatever you actually set.
Ozone, filter and strainer are built in. The strainer catches debris, the filter handles finer particulate, and ozone addresses what neither can. Together they extend how long water stays clear between changes.
The heating function is genuinely useful. The same unit can bring the tub up rather than down, so it is not dead weight in winter or for anyone who wants a warm soak instead.
Electrical & Installation — What the Manufacturer Documents
One caveat on the voltage figure. The manufacturer's published documentation states 120V for this range in one place and 110V in another. Both describe the same ordinary household circuit. Ask us and we will confirm the exact figure, and the amperage draw, with Dynamic Cold Therapy in writing before you order. Do not run the unit on an extension cord.
What is documented: the unit is rated for residential use and connects with 3/4-inch inlet and outlet fittings. At 14″ × 21″ × 21″ it needs a level, ventilated position beside the tub with clearance for airflow, within reach of the supplied 3-foot hoses unless you extend them.
On running costs: we do not publish an operating-cost estimate for cold plunge chillers. Duty cycle depends on your target temperature, ambient conditions, tub insulation and usage — none of which the manufacturer specifies. Any figure we quoted would be a guess dressed as a specification.
What Is Included, Size, Weight & Delivery
- Included: In and out 3 ft hoses (2 hoses), direct connect, 3 filters
- Unit dimensions: 14″ W × 21″ D × 21″ H
- Unit weight: 78 lb
- Colour: White
- Shipping dimensions: 18″ W × 26″ D × 25″ H
- Shipping weight: 105 lb
- Cartons: 1
- Delivery: UPS / FedEx Ground
This ships by ground carrier, not freight — a single 105 lb carton rather than a pallet. That is a real practical difference from the two 42-inch tubs, which require curbside LTL freight.
The supplied hoses are 3 feet each, enough for a unit sitting immediately beside the tub. If it needs to sit further away or behind a screen, plan for longer hoses — and consider insulated hose covers, because uninsulated hose between chiller and tub is a direct heat gain.
Warranty, Safety & Usage
- Manufacturer warranty: 1 year, plus lifetime product support
- Brand: Dynamic Cold Therapy
- Model: Premier Edition, DCT-SV-10DO3
- Country of manufacture: China
- Designated use: Residential
Note the warranty term. Dynamic Cold Therapy provides one year on this unit — shorter than the five-year term on the Golden Designs sauna range, and worth weighing on equipment with a compressor in it. Terms and claim procedures are set by the manufacturer and may vary by component.
Usage: Intended for residential use with a compatible cold plunge tub. Install on a level, stable, ventilated surface and operate according to the manufacturer's instructions. Follow the manufacturer's water-care and filter-replacement guidance.
Cold water immersion: Cold plunging places real stress on the cardiovascular system. Enter and exit deliberately, never plunge alone if you are new to it, and do not stay in longer than you are comfortable with. Leave the water immediately if you feel dizzy, disoriented, numb or unwell.
Medical disclaimer: This product is not a medical device and is not intended to diagnose, treat, cure or prevent any disease. Consult a qualified healthcare professional before using cold water immersion if you have a heart condition, high or low blood pressure, circulatory problems, a respiratory condition, are pregnant, use an implanted medical device, or have any question about whether cold immersion is appropriate for you.

Compare the Premier Edition Systems and the Tubs They Serve
Wellari carries both Premier Edition cooling and heating systems. They are identical in function, minimum temperature, control, water care and connection size, and differ in capacity and physical size.
- 0.8 HP — DCT-SV-08DO3. Up to 135 gallons, 1–3°F every 30 min. 13″ × 20″ × 18″, 62 lb, ships at 85 lb. The sensible choice for smaller barrels in typical conditions.
- 1.0 HP — DCT-SV-10DO3 — this page. Up to 150 gallons, 1–3°F every 20 min. 14″ × 21″ × 21″, 78 lb, ships at 105 lb.
The tubs these connect to are sold without a cooling system. Dynamic Cold Therapy lists the cooling system as optional on every barrel tub, and Wellari supplies them tub-only:
- Oval Barrel 50″ — DCT-BO-50-PLPC-34. Plastic-lined with Pacific Cedar exterior, 46″ × 26″ × 28″ interior.
- 42″ Barrel, plastic-lined — DCT-B-042-PLPC-34. 38″ × 33″ interior.
- 42″ Barrel, 304 stainless — DCT-B-042-SSPC-34. Same footprint, stainless interior.
How to choose. If the tub is small and lives indoors in a conditioned room, the 0.8 HP is enough. If it is larger, outdoors, in a garage, in a hot climate, or opened several times a day, take the 1.0 HP — the extra capacity shows up as a steadier temperature, not a lower one.

Common Questions
Should I take the 1.0 HP or the 0.8 HP?
Both reach the same 37°F minimum. Take the 1.0 HP if the tub is at the larger end of the range, sits outdoors or in an unconditioned space, your climate is hot, or the plunge is used and opened several times a day. The extra capacity buys a faster pull-down and a steadier hold, not a colder floor.
What electrical supply does it need?
A standard North American household outlet, with GFCI protection built into the unit. The manufacturer's documentation states 120V in one place and 110V in another — both describe an ordinary household circuit rather than a dedicated high-voltage supply. Contact us if you want the exact figure and the amperage draw confirmed in writing before you order. Do not use an extension cord.
Does it heat as well as cool?
Yes. It is specified as a cold and heat system with a range of 37°F to 85°F, so the same unit can bring the tub up as well as down.
How big a tub will it handle?
Up to 150 gallons — the larger of the two Premier ratings. The 0.8 HP unit is rated to 135 gallons.
How quickly does it cool?
Approximately 1–3°F every 20 minutes, depending on ambient temperature and water volume. That is faster than the 0.8 HP unit, which works at roughly 1–3°F every 30 minutes.
Is a chiller included when I buy a Dynamic tub?
No. Dynamic Cold Therapy lists the cooling system as optional on the barrel tubs, and Wellari supplies them tub-only. The chiller is a separate purchase.
What does it cost to run?
We do not publish a figure. Running cost depends on your target temperature, ambient conditions, tub insulation and cover, and usage — and the manufacturer publishes no duty-cycle data. Any number we gave would be a guess presented as a specification.
How is it delivered?
By UPS / FedEx Ground in a single carton weighing 105 lb. Unlike the two 42-inch tubs, it does not require curbside LTL freight.
What warranty applies?
Dynamic Cold Therapy provides a 1 year manufacturer warranty. Coverage and claim procedures are set by the manufacturer and may vary by component.
Why Buy From Wellari Wellness
Manufacturer Specifications, Stated Plainly
Wellari Wellness publishes current manufacturer specifications — capacity, temperature range, connection sizes, dimensions, weights, delivery method and warranty term — so you can compare on the facts rather than on marketing language. Where the manufacturer's own documents disagree, as they do on the voltage figure, both figures are stated; where a specification is not published at all, it is left off the page. Products are sourced through verified manufacturer, distributor or supplier channels.
Is 1.0 HP the right size for your tub?
Tub volume, location and how often you use it decide the capacity. Tell us the setup and we will confirm the right system — and get the exact electrical figure in writing if you want it before you commit.
