About us
Engineering, development and manufacturing of tanks and pressure vessels, since 1964
LAPESA GRUPO EMPRESARIAL, a family business founded in 1964 as a manufacturer of pressure vessels, has focused its main activity since its foundation on the manufacture and marketing of tanks and semi-trailer tankers for the storage and transportation of LPG, for the storage and transportation of LNG and other cryogenic storage gases, tanks for the storage of liquid fuels, and storage tanks for domestic hot water (DHW), as standard products. In its special manufacturing section, it builds pressure vessels for chemicals, refrigerant gases, hydrogen, ammonia or any type of fluid or gas for specific projects. Its three main factories and offices are located in the city of Zaragoza, occupying a total area of 95,000 m2, with 61,500 m2 covered. It operates mainly in the gas, oil, chemical, industrial and construction sectors, counting among its clients and distribution channels the main national and international companies and purchasing groups in these sectors.
DHW tanks in STAINLESS STEEL
The STAINLESS STEEL with chromium-nickel-molybdenum AISI 316 L, highly resistant to pitting caused by halogen elements such as the chlorine present in drinking water, is the material used to manufacture all of the models in our “GEISER INOX” and “MASTER INOX“ series.
Hygienic material and "Food Grade" by definition, enables high working temperatures without the need for cathodic protection.
Easy to clean, it allows the use of very energetic washing and disinfection means without altering it (e.g. treatments anti-Legionella).
DHW tanks made of stainless steel do not accumulate residues from the sacrificial anodes consumption, as they do not require cathodic protection under normal working conditions. The quality level of a stainless steel tank depends mainly on the way and quality of execution of the manufacturing processes, the design of the storage cylinder and the quality of the stainless steel used. The success of the lapesa products is closely related to the combination of these three aspects.
PRODUCT WITH EXCEPTIONAL QUALITY: The best kept secret. The manufacturing process of our stainless steel cylinders is the key to their success as a product of proven quality, obtaining a product with high performance and a long service life.
DHW tanks in ENAMELLED STEEL
VITREOUS enamelling process (steel surface protection treatment): VITREOUS enamelling for domestic hot water storage tanks is by far the most suitable lining of all those that exist on the
market for this type of product made of carbon steel that requires special protection of the metal surfaces in contact with water.
Vitreous enamelling is a food-quality, impermeable lining with a porcelain look that protects the metal surface of the storage tank in contact with water.
All internal linings in DHW cylinders must, by law, be "Food Grade" (EC Regulation 1935/2004). Our vitreous enamelling, in addition to food grade certification at the specified test temperature according to current regulations (22ºC), has food grade certification at 120ºC, which guarantees its maximum quality at extreme working temperatures.
Applying a sophisticated "surface treatment" to the steel surface together with an automated process for the application of the enamel, results in much more than just a good mechanical adherence of the lining. During the curing process a molecular interaction occurs between the steel surface and the applied enamel coat.
This maximum bonding of the enamel coat to the steel surface and the high degree of impermeability of the vitreous enamelling, guarantees the durability of the product and prevents the kind of deterioration that can occur with other types of coatings, such as the detachment or blistering of the protective coat.
It perfectly withstands the maximum DHW storage temperatures handled in this type of facilities (95 ºC), without deterioration or detachment, due to its capacity for molecular interaction with the steel surface. This treatment is carried out with the application of an enamel (inorganic chemical product) through a "dry" or "wet" process (depending on the type of tank and its internal geometry) and subsequent oven-curing at 850 ºC.
INERTIA storage tank
Inertia storage tanks for closed heating or cooling circuits, which act as an energy management system of the installation. Models with or without internal exchanger, and models with their own thermal stratification system, complete our range GEISER/MASTER INERTIA, from 30 to 6000 liters of storage capacity.
For installations where proper energy management is required, especially for systems that use renewable energy sources, such as BIOMASS, HEAT PUMP or SOLAR ENERGY. Designed for an extraordinary energy storage capacity, which translates directly into real savings. The extra-thick, rigid, mould-injected PU thermal insulation maintains the DHW storage temperature over long periods of time without requiring any additional energy input. This means less start-ups and adjustments of external energy sources, with less energy consumption and economic saving.
The GEISER INERTIA 800 and 1000 litre models are designed with a detachable insulation system on the two opposite sides of the tank to allow them to pass through 800 mm wide accesses.
Our “MASTER INERTIA” storage tanks are designed for easy handling and transport to the place of installation. They have an integrated system for handling and transporting by forklift truck, which facilitates handling operations enormously, as there is no need to palletize the product which, given its weight and size, would make handling difficult.
Models with an integrated THERMAL STRATIFICATION system, which allow an adequate energy management and its optimization for each specific use, at the lowest economic cost!

STAINLESS STEEL TANKS 'GEISER INOX'
LONG-LASTING PRODUCT: Nickel-chromium-molybdenum STAINLESS STEEL DHW storage tank, highly resistant to pitting caused by halogen elements such as chlorine in drinking water.
This is the material used to manufacture all of the models in our “GEISER INOX” series.
MAXIMUM STORAGE CAPACITY: Extra thick, rigid, PU mouldinjected insulation that minimizes heat losses of stored DHW.
'GEISER INOX' DOUBLE WALL TANKS
SELF-CLEANING EFFECT: Corrugated design of the DHW storage tank, in constant vertical movement depending on the fluctuations in the internal pressure, which helps to detach any
limescale from the walls.
ANTI LEGIONELLA DESIGN: Totally uniform DHW storage temperature, with no cold zones inside the storage tank. The surround heating of DHW produces a uniform water storage temperature
throughout the whole of the tank, which in turn allows it to be used to its full capacity.
MAINTENANCE-FREE: DHW tank without any internal heat exchange elements. It does not require cathodic protection in normal drinking water conditions. The models with electric heating
have the heating element in the primary circuit so there is no risk of corrosion or lime scale.
