API Energy offers Turnkey Solar Thermal Cooling System: Water is chilled in the district cooling plant and supplied to customer buildings through the network of pipes. The chilled water is fed into the building’s own cooling system through the heat exchanger, and then fed back to the cooling plant in a closed loop where it is chilled again and redistributed.
Solar thermal can power air-conditioning systems and industrial cooling processes. Solar thermal cooling systems with integrated Solar technology along with thermally driven absorption chillers with cooling tower reduce the conventional air-condition loads at a fraction of the costs and guarantee substantially lower operating costs
Cooling of buildings represents about 70 percent of the peak electricity load in the Gulf region.
Temperature level to be reached by solar field accounts to only 90-210°C which in return chills water down to 5-9° C.

API Energy offers Solar Field Collector System have central receiver (or solar tower) concentrator uses an array of planar mirrors to approximate the full 3D concentration and achieve high concentration. Each individual mirror tracks the Sun about two axes to focus light onto a receiver placed atop a central receiver tower.
Thermal storage is the concept of storing energy in form of heat. There are different approaches to storing large amounts of heat, one of the most promising is the concept of phase changing materials (PCM). These materials are capable of holding large energy amounts when changing from one phase into another. We know this effect from a simple ice cube. If you heat the cube up it stays at 0° C (273° K) until completely molten. The amount of energy used to melt an ice cube is equivalent to the amount you need to heat water to 80° C (353°K).
The same effect, but with a higher energy density, holds the molten salt storage concept, containing a mixture of 60 percent sodium nitrate and 40 percent potassium-nitrate, commonly called saltpeter. The salt melts at 430 F and is kept liquid at 550 F in an insulated cold storage tank. The salt is them pumped to the top of the tower, where concentrated sunlight heats it in a receiver to 1050 F. The receiver is a series of thin-walled stainless steel tubes. The heated salt then flow back down to a second insulated hot storage tank. The size of this tank depends on the requirements of the utility; tanks can be designed with enough capacity to power a turbine from two to twelve hours. When electricity is needed from the plant, the hot salt is pumped to a conventional steam-generating system to produce superheated steam for a turbine/generator.A turbine is a spinning wheel that gets its energy from a gas or liquid moving past it.
Operation Cycle:
A field of sun tracking mirrors called heliostats is used to reflect and concentrate the solar radiation onto the receiver (Step 1).
At Solar Reserve's Solar Two facility, molten salt is circulated through tubes in the receiver, collecting the energy gathered from the sun (Step 2).
The hot molten salt is then routed to an insulated hot thermal storage tank where the energy can be stored with minimal energy losses (Step 3).
When electricity is to be generated, the hot molten salt is routed to a heat exchanger (or steam generator) and used to produce steam at high temperature and pressure. The steam is then used to power a conventional steam turbine, generating electricity (Step 4).
After exiting the steam generator, the molten salt is sent to the cold salt thermal storage tank (Step 5) and the cycle is repeated.
Using molten salt.
Key advantages of using molten salts:
• 100% natural nitrate salts.
• Virtually maintenance free.
• High specific heat.
• High chemical stability.
• Non-flammable.
• Produced with much lower CO2 emissions and far less environmental impact compared to synthetically produced salts.
• Highly refined, low content of impurities

API Energy Offers Sludge Heat Exchanger to over come two very common issues in sludge or pasteurisation systems with their inherent inefficiency and fouling of the heat exchanger tubes due to the nature of the sludge or waste water material. API Energy concentric tube heat exchangers are designed to overcomes the fouling issues by using its corrugated tube in tube technology , together with cleaning-in-process (CIP) technology.

API Energy concentric tube heat exchangers are designed for heating sludge and organic waste in the anaerobic digestion process. Large inner tubes are used to eliminate blocking and allow heating of thick sludges to over 10% dry solids content. These are Tube-in-Tube corrugated tube heat exchangers specially designed for direct regeneration (product to product) between hot and cold sludge and biomass. Units are formed by two concentric tubes, and the transition between units is done by means of special clogging-free headers.

Wastewater treatment
Pasteurising food and agricultural wastes
Sewage sludge and biosolids treatment
Biogas feedstock pasteurisation
Pasteurising digestate from biogas production

We can also offer package unit to suit individual projects

API Energy offers scraped surface heat exchangers for applications where either one or both side require special solutions.

Fouling occurs when fluids degrade near the tube wall and layers of solids deposit or stick to the tube wall causing performance to drop or due to crystallisation components in the fluid change to the solid state and deposit on the heat exchanger surface.

Viscous fluids require a large heat transfer area. Scraped surface heat exchangers mix the fluid vigorously, which helps to move the fluid to and from the heat exchange surface. This increases heat transfer rates, so total area required for heat exchange is reduced.
