Smooth operator

Hitachi has recently released its SmoothDrive 2.0 technology as part of its updated Hitachi Variable Refrigerant Flow (VRF) air365 Max Pro.

The company says this technology contributes to the very high levels of energy efficiency defining the Hitachi VRF HVAC solutions, under part load operation.

“The SmoothDrive 2.0 further improves efficiency, particularly at 10 to 35 per cent part load thanks to its 0.1°C temperature monitoring sensitivity,” Hitachi says. “The SmoothDrive 2.0 helps the scroll compressor to run continuously and smoothly, even under part load conditions.”

Hitachi says the integration of inverter technology into SmoothDrive 2.0 is key for greater accuracy of the overall refrigerant flow.

“Hitachi SmoothDrive 2.0 continuously tracks the indoor temperature in each zone and identifies gaps with the set temperatures,” the firm says. “Combining real‑time indoor monitoring and the VRF system datapoint, SmoothDrive 2.0 constantly calculates the right amount of refrigerant needed to maintain seamless indoor comfort.”

Hitachi says SmoothDrive 2.0 contributes to 39 per cent less energy consumption at 33 per cent part load operation.

“In addition, the all new Sigma shaped heat exchanger and gas injection scroll compressor extend the compressor operating range and increase heating or cooling capacity, leading to a wider outdoor unit operating temperature range and better efficiency,” Hitachi says. “As a result, the air365 Max Pro attains unparalleled efficiency performance.” Go to www.hitachiaircon.com/au/ ■

2 Dwyer releases IDPT transmitter

Dwyer has released its industrial differential pressure transmitter, the Series IDPT.

“These transmitters feature a rugged housing and highly stable accuracy for a long service life in most industrial applications, including semiconductor, pharmaceutical, laboratories, fume hoods, HVAC pressure, critical measurement, and high purity,” Dwyer says.

“The Series IDPT Industrial Differential Pressure Transmitter features a rugged, water resistant housing and highly stable accuracy for a long service life in most industrial applications,” Dwyer continues. “This pressure transmitter utilises a capacitive pressure sensor on ranges 0 to 0.25 in w.c. to 0 to 1 in w.c. and a piezo sensor on ranges 0 to 2.5 in w.c. to 0 to 10 in w.c., both of which offer accuracy options of 0.25 per cent or 0.5 per cent full scale.”

Dwyer says the cap cell allows the IDPT to maintain critical processes in industrial applications. The series offers a 4–20mA 2 wire version for a loop powered current output as well as a 0–5V/0–10V selectable voltage output version.

Hi-Flo upgraded

Camfil has upgraded its Hi Flo brand of bag filters for ePM1 60 per cent and ePM10 60 per cent efficiencies.

“With customers facing dramatic increases in energy costs as well as societal demands for all companies to act more sustainably,” says the company, “the new Hi‑Flo upgrade has been designed to support both of these key aspects for building owners.”

According to Camfil, the Hi Flo bag filter has been used for more than 50 years in a full range of buildings

– from pharmaceutical production and hospitals to office buildings and commercial centres – to help protect people, processes and the environment. The product has been manufactured with a focus on energy saving properties, as well as stable and reliable performance.

“With this product upgrade, current Hi Flo users will be able to reduce energy consumption without changing anything,” says Camfil. “By converting non‑Hi‑Flo users or choosing a higher performing filtration class, this figure can be more than twice as big.”

Camfil says the upgraded filters also reduce energy consumption, which will reduce emissions, and provide savings for end users.

4 Fujitsu’s high times

Fujitsu General has introduced a new high static R32 ducted air conditioning range that it says delivers an innovative blend of sustainability, compatibility, useability and high performance. The new range includes single phase R32, single phase R32 high performance (HP), and three phase R32 models.

Fujitsu says the indoor units all feature the same lightweight and compact chassis design, meaning the range is able to fit in tighter spaces and is easier to manoeuvre, providing greater compatibility and convenience for installers. Similarly, the outdoor unit is also smaller to enable more flexibility to install in narrower spaces, with 500mm of clearance required at the front of both the single and double fan outdoor units.

Fujitsu General Head of Product ANZ Kyle Rafter says the models have a 67 per cent lower global warming potential factor than R410a, while still maintaining performance.

“The High Static R32 ducted range is part of Fujitsu General’s ongoing commitment to lowering the global warming potential of its products, while providing an enhanced product experience for both installers and consumers,” Rafter says.

The High Static R32 range features automatic static pressure adjustment and custom auto mode. These allow the cooling and heating modes to maintain different set points, enabling the unit to automatically switch between heating and cooling modes to maintain a desired room temperature between two temperature set points, the company says.

“All models have a maximum guaranteed ambient operating temperature range of up to 50°C in cooling mode, have demand response, and are zone system compatible,” says Rafter. Go to www.fujitsugeneral.com.au ■

5 Twice as nice from CSR

Building products company CSR has launched two new online tools: the CSR System Selector and CSR Thermal Calculator. From selecting the optimum system for a project to understanding the thermal qualities of walls, roofs and floors, each platform is designed to offer comprehensive design information and complete system solutions, which are constantly updated with the latest innovations in technology and product developments.

“We have worked hard to deliver comprehensive and easy‑to use platforms that respond to our customers’ needs,” says Gary May, EGM CSR Customer Solutions.

The CSR System Selector helps choose the right building systems for projects. The selector is backed by CSR to ensure that each system will satisfy design and building code requirements.

The CSR Thermal Calculator generates thermal performance calculations for wall, roof and floor systems.

“CSR has one of Australia’s largest portfolios of building materials manufacturers for construction of homes and commercial buildings,” says May. “The new digital tools will be of considerable benefit to experts in the industry looking to secure the best possible outcomes for their customers by providing solutions backed by CSR’s trusted name.”

6 Ductmate goes Pro

PROflex is a flexible duct connector designed to isolate equipment noise and vibration from ductwork. It consists of a fabric secured to sheet metal on both sides. Typically, the connector is inserted between the equipment and the ductwork. PROflex is available in various lengths: 305m, 229m and 152m. Custom sizes and lengths are available to meet specific production needs.

Ductmate says that PROflex master rolls, when used with any automated flexible duct connector machinery, will significantly reduce labour time and machine downtime, resulting in savings. A PROflex 305m roll will also significantly reduce the scrap produced compared to the standard 30m roll, according to Ductmate.

“With the unsurpassed high quality of Ductmate’s PROflex, why waste any of the product,” the company says. “The more you use, the more you save.”

“An automated flexible duct connector machine used with PROflex master rolls will also allow you to take the guesswork and the possibility of user error out of the cutting process.”

7 HEVAC’s CO carpark controller

HEVAC, an Australian company specialising in control systems for the commercial air conditioning industry, has a new offering in its range of carpark CO control systems.

The new SACO is a standalone wall mount sensor/ controller that complies fully to Standards Australia AS 1668.2‑2012 for CO management, fan fault monitoring and minimum timed ventilation requirements, says HEVAC. According to the company, the Australian designed and manufactured SACO is suited for small, enclosed motor vehicle garages and lockups with poor or no natural ventilation not exceeding 25m sensing from the monitor.

The SACO is capable of direct control of on/ off fans up to 5 amps or variable speed control of VSD or EC controlled fans, the company says.

For larger area systems, HEVAC recommends its HCP7 CO controller with the required number of remote wall‑mounted HGSU CO sensors to suit the size of the carpark.
