Import Drain Back — Buy in Bulk from Supplier in India

The Drain Back is a closed‑loop, indirect solar water heating system supplied by Kaltech Energy, based in India. It circulates a thermal medium - either water or a glycol‑water mixture - through solar collectors to an underground storage tank, using a dedicated pump that activates only when heat is needed. The system incorporates an electric backup heater with auto temperature control and offers remote monitoring and control options for precise temperature management. This design eliminates overheating risks and allows the storage tank to be positioned below the collector, with sloped interconnecting pipes to ensure proper drainage.

Typical installations use a glycol‑water blend as the heat‑transfer fluid because of its low freezing point and high thermal stability; the blend is often a 30 % glycol, 70 % water mixture in similar systems. The circulator pump is usually a small‑capacity, variable‑speed unit that matches the collector area, providing efficient heat transfer while minimising electricity use. A standard system of this type delivers around 200 L of hot water storage, achieves a temperature rise of roughly 40 °C, and operates at an overall thermal efficiency of about 60 % under optimal solar exposure. These figures are common in the industry for residential and small‑commercial applications.

Kaltech Energy targets builders, EPC contractors and facility managers who require reliable hot‑water solutions for hotels, hospitals or multi‑unit residential projects. The listing does not disclose minimum order quantities, pricing, lead times or specific certification status, so prospective buyers should request those details directly. Shipping is generally organised from the supplier’s base in India, with packaging that protects the collector panels and storage tank during transit. Confirming the exact system capacity, pipe sizing and control interface with the supplier will ensure the solution integrates smoothly with your project’s design.

Kaltech Energy lists its address as Churchill Tower, Business Bay, Dubai United Arab Emirates, though the product origin is recorded as India. The supplier holds a harbour trust tier on the platform, indicating basic verification, but its response rate is currently 0.00, meaning no replies have been recorded to buyer enquiries. The company’s profile highlights a focus on solar thermal technologies, with the Drain Back system forming part of its renewable‑energy product line.

The Drain Back listing does not provide details on certifications, minimum order quantities, pricing or lead‑time. Potential buyers are advised to contact Kaltech Energy directly to obtain a technical datasheet, confirm system sizing, and discuss any required compliance documentation such as ISO 9001 or relevant safety standards.
