Hyperchill BioEnergy | Water Chiller for Biogas Applications – Domnick

Description

Bioenergy is renewable energy stored in organic materials such as plant matter and animal waste, known as biomass. The wide variety of biomass fuel sources include agricultural residue, pulp/paper mill residue, urban wood waste, forest residue, energy crops, landfills and animal waste. Anaerobic digestion is the process that occurs when bacteria decompose organic materials in the absence of oxygen to generate biogas.

Biogas is primarily composed of methane and carbon dioxide with smaller amounts of hydrogen sulphide and ammonia. Trace amounts of other gases like hydrogen, nitrogen or carbon monoxide are also present in the biogas. Usually the mixed gas is saturated with water-vapour and may contain dirt particles. For biogas as a fuel, most of the impurities have to be removed, as they can cause contamination, deposits and damage to equipment. In particular, biogas needs to be dried by cooling it to temperatures close to 5 °C, using water-cooled heat exchangers fed by water chillers. Hyperchill Bioenergy is a key component in this biogas treatment process.

Extremely compact and easy to use, Hyperchill Bioenergy ensures an accurate control of the water temperature. It has been specifically designed for Biogas applications and provides safe and reliable operation in the harshest of environments, typically found in Anaerobic Digesters and landfill Biogas production areas.

Features and Benefits:

Special protective treatment of condensers and copper piping to ensure reliable operation in the most aggressive of ambient atmospheres at biogas plants and landfill sites.
Pump and tank installed inside the chiller provides a compact and easy to install solution.
Closed water temperature operation with high working limits and low running costs.
Large built-in water tank that provides a large thermal mass / storage capacity thus reducing the number of refrigerant compressor stop/starts and short cycling and thereby increasing the compressor and chiller lifetime
Designed to provide cooling water where low temperature water is required as standard (Air Conditioning units do not normally need to provide water at less
than 10 °C).
Use of compliant scroll compressors designed specifically for high efficiency and long life in industrial applications.
Low ambient speed-control on fan-motor ensures constant performances at different temperatures, long lifetime of the fans and a reduction in absorbed power when ambient temperature is low.
Maximum working ambient temperature up to 48 °C for ICEP models, up to 45 °C for ICE models, prevents downtime even under extremely harsh conditions

The performance of biogas as a fuel depends on effective cooling and treatment. Saturated biogas contains water and impurities that need to be removed to avoid damage to equipment and to reach more efficient combustion, whilst maintaining the desired dew point.

Water and refrigerant manometers permit full control of the working conditions.
Microprocessors: allow complete control of the unit parameters. Proprietary software allows a wide range of programming and remote monitoring options.
Compliant scroll compressors: with less moving parts and compliant-technology, they provide excellent efficiency, high reliability, and very low noise levels.
Air cooled with axial fans: suitable for outdoor installation.
Water pump (std 1,5 bar): available with different head pressures to suit the end-users application. Configurable as a twin-system, for 100% redundancy.
Mesh filters: condenser protection against dirt and contamination, reduces maintenance costs and the risk of downtime.
Evaporator: located inside the water tank from ICE076 – reduces the overall dimension of the unit, increases the efficiency and improves temperature control.
Water by-pass: protects the pump and supplies constant flow to the evaporator, avoiding alarms and freezing.
Water tank: stainless steel up to ICEP060 generously dimensioned to guarantee high reliability and improved temperature-control.
Models from ICEP020 to ICEP060 designed with fan control in order to work as standard in low ambient temperatures down to -10 °C.
Maximum ambient temperature 48 °C up to ICEP060, 45 °C from ICE076.
MODBUS interface fitted on ICEP models; optional for ICE model

Options

Special and multiple-pumps: higher (P30-3bar) head pressure available to suit different hydraulic circuits. Double stand-by pump for greater reliability.
Antifreeze heating: avoids freezing when the unit is switched off. Can also be used as a heater to warm up the system.
Water fill-kits: pressurized, automatic or ambient manual kits, for water filling in any installation.
Remote control kits: base version for remote ON/OFF and general alarm monitoring. Advanced version for complete remote unit management.
Wheels (up to ICEP014 BioEnergy): for ease of transport.
