Water-Based Cooling · Water-Based Heating · External Control Unit with Top Panel and Carry Handle · Corrugated Connection Hose · Textile Bag with Zippered Edge · OEM / ODM
This is a water-based sleep temperature system made of three components: a control unit that conditions the water, a sleeping bag that the water circulates through, and a corrugated connection hose that joins them. The unit runs either a cooling mode or a heating mode, and the same bag serves both.
The design answers a problem that a fixed sleeping bag cannot. A bag is built for a temperature band — too warm a bag is unbearable in summer, too light a bag is cold in winter, and a camper ends up owning two. A water loop moves heat in either direction, so one bag covers the range.
Because the unit sits outside the bag, the bag itself stays thin, free of batteries, and packs and stores like an ordinary sleeping bag. The hose is detachable, so the bag can be used independently of the machine.
The reference material labels the coloured overlays and the circulation arrows as illustrations of the mode. They are visualisations, not thermal images, and this page treats them that way.
This page describes a configurable platform. Bag design, colourway, branding and packaging are specification items, and the control configuration and hose routing are confirmed against the approved sample.
It is a water-based cooling and heating system for a sleeping surface. It changes the temperature of the surface you sleep on.
It is not a life-safety or survival device. It does not replace the temperature rating of a sleeping bag, and it must not be relied on to prevent hypothermia. Insulation and judgement do that job; an appliance does not.
It is not a medical device, and it is not a therapy device. It makes no claim about sleep quality, circulation, pain or any other condition.
And it is not a battery product. The unit is a mains-type appliance that stands beside the bag, and its electrical specification is confirmed per project.

The loop has three parts and one job: move heat between the unit and the bag.
| Part | What it does |
|---|---|
| Control unit | Conditions the water — cooling it in one mode, heating it in the other. Stands upright on the floor beside the bag |
| Connection hose | Carries the water between unit and bag. A corrugated sleeve with a connector at the unit end |
| Sleeping bag | The surface the water runs through. The textile surface transfers heat between the loop and the sleeper |
Because the loop is reversible, the same hardware serves both modes. That is the structural difference between this and an electric heated bag, where a heating element can only add heat.
Actual hose routing and port positions are confirmed on the approved sample.
The unit is a tall black case with a flat top. Three features matter.
The top control panel places the cooling and heating controls on the upper face, where you can reach them from a sleeping position without kneeling. The carry handle is what makes it portable rather than a fixture. And the vented side is the detail that decides whether the system performs: the unit conditions water and rejects heat, so it needs air. Covering it, or pushing it into the bag, is the easiest way to make it work badly.
The control configuration is confirmed against the approved sample. We do not publish a button map, because the panel layout varies between programmes.
The bag is a textile surface with a zippered edge, with a small pillow or pocket at the head end in the reference images.
The textile has two jobs: transfer heat between the water and the sleeper without feeling like a plastic sheet, and survive being folded, rolled and packed between trips. The zippered edge is what makes it a bag rather than a mat, and it has to be workable in the dark.
Fabric composition, filling and exact construction are confirmed on the approved sample, because those are the parts most likely to be specified per market.
A water loop, an electrical unit and a person asleep is a combination that deserves plain rules.
This product is not a medical device. It is not intended to diagnose, treat, cure or prevent any disease, and it makes no claim about sleep quality, circulation, pain or any other condition. It changes the temperature of a sleeping surface only.
| Item | What can be set |
|---|---|
| Bag design | Reference material shows three design directions |
| Colour and branding | Reference swatches plus branding options |
| Private label | Your branding on the system |
| Packaging | Custom packaging designs |
| Configuration | Cooling and heating modes at the main unit |
The reference artwork labels the design, colour and packaging options as concepts, subject to the confirmed sample. They are directions a programme can take, not a fixed catalogue with part numbers.
| Step | Stage |
|---|---|
| 1 | Brief — market, sleep configuration, bag design direction, colourway, branding and quantity |
| 2 | Design Review — unit specification, bag construction and a written specification for your approval |
| 3 | Sample Approval — you confirm the bag construction, hose fittings, control layout and branding |
| 4 | Order Spec — the confirmed specification is recorded before production |
Process and options subject to confirmed order.
OEM and ODM here describe the project enquiry route, not a promise of unlimited variation. The available options and the supplied-item list are confirmed against the approved sample and the confirmed order.
| Before ordering, confirm | Why it matters |
|---|---|
| Sleep configuration | Outdoor camping, indoor rest space, or both — it changes the bag design |
| Bag design direction | Reference material offers three; confirm the pattern before sampling |
| Colourway and branding | Swatches plus branding method, settled early |
| Packaging | Custom packaging is a print job in its own right |
| Site conditions | The unit needs floor space and ventilation wherever it will run |
Final details follow the approved sample.
We would rather hand you a sample, a drawing and a written specification than a headline number that will not survive a buyer’s compliance review. If a figure is a hard requirement for your programme, raise it at the design stage and it becomes a defined, testable specification.
Dongguan Sheerfond New Material Co., Ltd. develops and manufactures far-infrared and graphene heating materials, and designs thermal systems built around them — in both directions. Our low-voltage heating range covers 3.7 V, 5 V, 12 V, 24 V and 36 V architectures, and our cooling programmes apply the same principle in reverse: moving heat out of a surface or a volume rather than into it. This sleep system is a water-based programme in that second family.
Products are manufactured against project specifications with batch inspection records.
Send us the market, the sleep configuration you are planning, the bag design direction and colourways, your branding and packaging requirements, and your target quantity. If the system has to match an existing sleep range, send the dimensions and we will work from those.
Price indication: quoted per project, because the unit specification, bag design, branding and order size all move the number.

This product is not a medical device and is not intended to diagnose, treat, cure or prevent any disease. It changes the temperature of a sleeping surface only, and makes no claim about sleep quality, circulation, pain or any other condition. It is not a life-safety or survival device and must not be relied on to prevent hypothermia. Keep the control unit ventilated and uncovered; route the hose clear of the body and of anything that could crush it; do not run the system unattended for long periods; stop immediately if water leaks; not for unsupervised use by children. Temperature, voltage, power, water capacity, dimensions, control configuration, hose routing and certification status are confirmed per project against the approved sample. Colour overlays in the reference artwork are mode illustrations, not thermal imaging.
