Riello NXHM Inverter Monobloc Air-Water Hydronic Heat Pumps

NXHM is an energy efficient residential hydronic heat pump for heating, cooling and eventual. domestic hot water production. The unit works with ecological refrigerant R32 ensuring not only a low global warming potential (GWP) and CO 2 emissions, but also a high energy efficiency throughout the working range.

NXHM is also equipped with new exchange coils with the special Blue-Fin hydrophilic and anti-corrosion treatment, which improves the drainage of condensate on the fins, thus reducing the risk of freezing on the coil (maximum efficiency even in humid climates)

NXHM is available in 10 different models with heating capacities from 4.2 to 15.9 kW

  • Twin-Rotary compressor with DC inverter technology, which modulates the power required to adapt perfectly to the actual load required
  • High COP and EER (all NXHM heat pumps comply with the highest required standards in terms of energy efficiency)
  • Third party certified performance HP Keymark Can be connected to low temperature radiators, underfloor heating elements and fan coil type units
  • Water heating temperature up to +65 °C - Quick and easy installation
  • Low noise unit
  • Wired control included, it can completely manage a heating/cooling/domestic hot water system
  • The control can manage up to 6 units in cascade (1 master and 5 slaves) even with different powers
  • Standard anti-freeze protection that protects the entire system and especially the hydraulic parts from potential frost damage.

Structure

Cover cabinet made of steel sheet painted with neutral RAL 7035 powders which increases its resistance to corrosion by atmospheric agents. All panels are removable

Compressor

A double compressor protection shield for sound isolation further reduces sound levels. An advanced technology, able to offer the maximum energy efficiency and characterized by a high power available in peak conditions, as well as an optimized efficiency at low and medium compressor speeds. The NXHM heat pump is equipped with DC inverter technology, which combines two electronic regulation logics: go modulation (PAM) and pulse width modulation (PWM), in order to guarantee optimized compressor operation in each operating condition, minimize temperature fluctuations, and provide perfect comfort regulation and, all while significantly reducing energy consumption

WFP extension

DC pulse width modulation drives the compressor to peak load conditions (startup and peak load), so that the voltage increases at a fixed frequency. The compressor runs at high speed, in order to quickly reach the desired temperature

PWM

DC Pulse Width Modulation controls the compressor in partial load conditions, adapting the frequency in the presence of a fixed voltage. The speed of the compressor is precisely regulated, and the system offers a high level of comfort (absence of temperature fluctuations) under operating conditions characterized by exceptional efficiency. The compressor frequency increases steadily until it reaches the maximum level. This guarantees the absence of intensity peaks during the start-up phase and, moreover, guarantees a safe connection to a single-phase power supply, even for high-power systems. This compressor start logic makes "Soft Start" starters useless and, moreover, guarantees the immediate availability of maximum power

External battery

The external coil is made with copper pipes and hydrophilic aluminum fins. This solution allows the water to migrate more easily (by gravity) towards the bottom of the exchanger. In particular, this innovation allows:

  • lengthening of the time necessary for the formation of frost, reducing the accumulation of the latter on the coil
  • a more efficient defrosting phase, thanks to the improvement of the water flow on the fins; thus, operation in heating mode is improved

Standard blue coating treatment which improves the resistance of the coils to corrosive agents and is recommended in all those applications with a moderate risk of corrosion

External Fan

Single variable speed Brushless DC fan motor for optimum air distribution together with extraordinarily low sound levels. Possibility of setting two different maximum noise levels

Electronic expansion valve

The electronic expansion valve is an electronic biflow expansion device, whose task is to optimize the volume of the refrigerant fluid present in the circuit and consequently the overheating, preventing the return of the fluid in the liquid phase towards the compressor. This device further improves the high efficiency and reliability of the system, as it also allows you to work with very low condensing pressures throughout the working range.

Solenoid valve

Given the extensive working fields of the unit, the solenoid valve, completely managed by the unit, allows the compressor to work at always optimal temperature levels

Plate heat exchangers

Vertical type plate heat exchanger in AISI 316 stainless steel

Integrated hydronic unit

The hydronic module is always present and is supplied with a variable speed circulation pump, flow switch, 3 bar safety valve, expansion tank and inlet and outlet water temperature probes. It is possible to have the backup electric heater as an accessory. In domestic applications, it is possible to connect the inertial storage tank directly below the unit in order to reduce the space occupied inside the living areas to a minimum. All internal hydronic parts are insulated to reduce heat losses. The antifreeze program contains special functions which use the heat pump and backup heater (if available) to protect the whole system from freezing. When the temperature of the water flow in the system drops to a certain value, the unit will heat the water, either with the heat pump, electric heating tap or backup heater (if available). The frost protection function is deactivated only when the temperature rises up to a certain value

However, the risk is transferred to the consumer as soon as the goods are delivered to the carrier. The Customer who at the time of purchase has decided to make use of the extra insurance service for the transport of the purchased goods, in the event that he finds anomalies at the time of delivery (packaging damaged or otherwise altered in the closing seals, damaged product or scratched, missing one or more packages ordered), must accept the product by writing on the document provided by the carrier: "WE ACCEPT WITH RESERVE" + description of the anomaly found. In fact, to enforce the insurance coverage it is not sufficient to note "ACCEPTED WITH RESERVE" or "ACCEPTED WITH SUBJECT TO INSPECTION", BUT the reason for the reservation must be explained in detail. If the package or the product should show visible damage, scratches or any other type of anomaly and the courier should refuse to affix a specific reserve, the goods must be refused and the incident reported immediately (and in any case in a timely manner) to the Customer Service of Decidiprice srl. In any case, without prejudice to the seller's obligations in terms of legal guarantee pursuant to articles 128 et seq. of the Consumer Code, Decidiprezzo srl will not be held responsible for any anomalies found in the state of the product, after delivery, if the Customer, in the presence of an anomaly, has accepted the package without making a specific reservation (in the corrected above). Any damage or anomalies must be reported to Customer Service by email to postvendita@climaconvenienza.it. The request must be forwarded no later than 8 calendar days from receipt of the goods.
