The power efficiency unparalleled

In 1998, Maxa has offered to the market the first air-conditioning

system with Variable Refrigerant Volume. This new range of products

is mainly characterized by its high efficiency and energy saving.

Thus began a long history that goes on for over 14 years, subject to

continued success thanks to the careful search in order to achieve high

efficiency as well as the improvement of energy saving. From the first

manufacturing of R22’s appliance that can only connect 6 indoor units

and where the minimum ambient operating temperature is of -5°C,

today with the new R410A’s modular systems allowing you to connect

up to 64 indoor units, fans and inverter compressors and with outdoor

operating temperatures down to -15°C.

The success of this technology is major, while in 2005 some of its

benefits have been extended even to small commercial applications

such as the first production of Mini Marv system. This system is

designed using all the innovations included in the big machines that

are dedicated for applications of up to 6 rooms. However since 2008,

with the introduction of the series models of MARV3 has created new

scenarios, the challenge now is to find alternative systems for primary

heating of large buildings. The knowledge of these systems and the

long laboratory tests allow to offer to the market compact models

giving better performance, with outdoor operating temperature in

heating mode of -15°C, high efficiency compressors and a sophisticated

electronic heart make up the system to ensure high efficiency and

safety thermal performance in winter. From that moment the door is

opened towards the systems that do not fear the cold winter, we have

marked a new chapter in this way with the production of the system

MARV4. The first set out of MARV’s system allows intelligent automatic

adaptation and precise control. The high efficiency and energy saving

are always on the agenda.

Il MARV di quarta generazione,

la macchina è completamente

rinnovata; nuovo ventilatore, nuovo

profilo pale, compressori Inverter

ad altissima efficenza, motore

ventilatore DC brushless. I valori

di EER e COP sono stati spinti

rispettivamente fino a 4,29 e 4,39.

Viene presentato il sistema a 3 tubi

per una contemporanea funzione

in riscaldamento e raffrescamento.

Here is the fourth generation of

MARV systems, the appliance is

completely renewed; new fan, new

blade profile, high efficiency inverter

compressors, DC brushless fan

motor. The E.E.R. and C.O.P. values

have been improved up to 4.29 and

4.39 respectively. We report a 3-pipe

system with simultaneous heating

and cooling operation.

2016

La serie MARV5 offre un ampio

range di unità esterne con

ventilatori ad alta prevalenza. I

modelli 8 e 10 HP hanno un unico

compressore inverter a differenza

dei modelli da 12 e 16HP che

utilizzano più compressori dei

quali uno sempre inverter al

fine di massimizzare l’efficienza

energetica. La serie ha aumentato

la sua flessibilità d’installazione

maggiorando i limiti imposti per le

distanze: 1000 m totali di tubazioni,

110 m di dislivello massimo al fine

di aumentare le possibilità di servire

edifici di maggiori dimensioni.

MARV5

series

incorporates

numerous outstanding features,

including large-capacity outdoor

and indoor units and high external

static pressure. The 8HP and 10HP

units use only one DC Inverter

Compressor, 12HP to 16HP units

feature higher capacity DC inverter

compressors, and adopt energy-

saving technologies. This series

provides an incredible piping length

of 1,000m and a level difference of

110m, making it perfect for large

high-rise buildings.

2018

La serie MARV6 è stata adattata

alle nuove esigenze progettuali e

di efficienza energetica. Le unità

hanno beneficiato di un aumento

generalizzato del COP. Nelle

versioni a 2 compressori, entrambi

i compressori sono gestiti tramite

inverter.

MARV6

outdoor

units

are

compliant to the latest energy

efficiency and design rules.

The COP is improved on all the range

and double compressors version

are now equipped with inverter

control on both compressors

2020

L’introduzione della nuovissima

gamma di unità esterne a flusso

di refrigerante variabile MARV7i

permette di realizzare sistemi di

potenza elevata (fino a 76,7kW

in freddo) senza la necessità di

usare più di una unità esterne. Tale

possibilità permette una riduzione

dei costi e numerosi vantaggi

installativi

MARV7i outdoor units range is now

available for being able to build very

high capacity systems (up to 73kW

in cooling capacity) with only one

outdoor unit. This feature allows for

reaching lower installation cost and

some installation advantages due

to the lesser surface occupied and

simpler refrigerant piping.
