Product Overview
The Commercial Non-pressurized Solar Collector System is a mature solar thermal engineering solution designed for centralized hot water supply in commercial, industrial, and institutional applications.
Delantherma is a manufacturer specializing in OEM and EPC-oriented solar thermal systems. Our products are supplied to EPC contractors, engineering firms, system integrators, and project developers involved in hotel, industrial, and public infrastructure hot water projects across the Middle East, Africa, Southeast Asia, and Latin America.
The system is engineered for real-world project conditions, with scalable configurations ranging from small commercial installations (approximately 1,000L/day) to large centralized systems exceeding 100,000L/day. It is suitable for phased EPC construction and large-scale infrastructure development.
Engineering & Manufacturing Capability
Delantherma provides integrated manufacturing and engineering support for solar thermal EPC projects, including:
- Flat plate and evacuated tube solar collectors
- Stainless steel insulated hot water storage tanks
- Hydraulic circulation system design for centralized heating projects
- Integration with auxiliary heating systems such as boilers, heat pumps, and electric backup units
- Project-based customization according to engineering drawings or technical specifications
We support EPC contractors throughout project development stages, including system sizing, technical coordination, and documentation preparation.
Project Experience
Our systems have been supplied through EPC contractors for installation in various international projects, including:
- Hotel centralized hot water systems in the Middle East region (mid to large-scale developments)
- Institutional dormitory and accommodation heating systems in Africa
- Industrial hot water process systems in Southeast Asia manufacturing sectors
- Agricultural greenhouse heating systems in North Africa controlled environment projects
In standard EPC procurement practice, detailed project references, system drawings, and technical performance documentation can be provided upon request for qualified buyers under NDA (Non-Disclosure Agreement).
Typical engineering performance targets include:
- 50%–75% reduction in conventional energy consumption
- 2–4 years estimated return on investment depending on energy cost and solar conditions
- 15–25 years system service life under proper maintenance conditions
Certifications & Quality Standards
Depending on project requirements, our systems can be manufactured in compliance with internationally recognized standards, including:
- ISO 9001 Quality Management System
- CE conformity for European market projects
- EN / ISO solar thermal performance testing standards
- Factory Acceptance Testing (FAT) for EPC and government-level projects
Each system can be inspected, tested, and documented prior to shipment based on project-specific technical requirements.
System Application Scope
The system is widely used in the following applications:
- Large-scale hotel hot water systems (100–500+ rooms)
- Industrial manufacturing hot water supply systems
- Hospitals and healthcare infrastructure projects
- Educational institutions and dormitory complexes
- Mining camps and remote infrastructure developments
- Agricultural greenhouse heating systems
- Swimming pool heating systems
