What is a Hot Water Tank?
Hot water tanks, also known as vessels or boilers, are used in the generation and storage of hot water. Hot water is required for a large range of commercial and industrial processes, including kitchens, bathrooms, cleaning, wood drying, green houses, central heating, and other industrial processes. Water is also a good heat storage medium and is thus used in many heat recovery applications.
Certification
Macrotec is certified to the following standards:
ISO 9001:2015 | Quality Management Systems
ISO 14001:2015 | Environmental Management Systems
ISO 45001:2018 | Occupational Health & Safety Management
Design
Vertical & Horizontal
Our tanks and pressure vessels are available in either a vertical or horizontal orientation, depending on your requirements and plants space. We normally recommend vertical tanks due to better water stratification between the hot and cold areas, as well as having a reduced footprint.
