Environmental Product Declaration: Danfoss Pressure Switch KP 1 – KP 7BS

Introduction

This Environmental Product Declaration (EPD) follows the Danfoss Product Category Rules (PCR) (2022-09-20). These rules provide a consistent framework for calculating and reporting the environmental performance of Danfoss' products and are aligned with relevant international standards, particularly ISO 14025:2006 and EN 15804+A2:2019.

This document has been produced by Danfoss A/S following an internal verification process, but it is not a third-party verified document.

What is an EPD?

An EPD is a document used to communicate transparently, the quantified environmental impacts of a product over its lifecycle stages. This quantification is done by performing a Life Cycle Assessment (LCA) in line with a consistent set of rules known as a PCR (Product Category Rules).

An EPD provides:

• A product's carbon footprint together with other relevant environmental indicators, including air pollution, water use, energy consumption, and waste, over its life cycle (Module A-C), as well as the expected benefits of reuse and recycling in reducing the impact of future products (Module D). See Table 1 for module descriptions.
• Environmental data allows customers to calculate LCAs and produce EPDs for their products.

Type of EPD

This EPD is of the type 'cradle-to-gate with options' and includes all relevant modules: production (A1-A3), shipping (A4) and installation (A5); deconstruction (C1), waste collection and transport (C2), treatment (C3) and disposal (C4). It also includes potential net benefits to future products from recycling or reusing post-consumer waste (D). The codes in brackets are the module labels from EN 15804+A2.

Modules concerning the use, maintenance, repair, replacement, refurbishment and operational energy and water use (B1-B7) are excluded, following the cut-off rules from EN 15804.

Product Description

KP pressure switches are for use in refrigeration and air conditioning systems to give protection against excessively low suction pressure or excessively high discharge pressure. It is also used for starting and stopping refrigeration compressors and fans on air-cooled condensers. It can be connected directly to a single-phase AC motor of up to approx. 2 kW or installed in the control circuit of DC motors and large AC motors. KP pressure switches are fitted with a single pole double-throw (SPDT) switch. The position of the switch is determined by the pressure switch setting and the pressure at the connector. KP pressure switches are available in IP30, IP44 and IP55 enclosures.

The EPD covers all products in the KP Pressure switch product group referenced in Annex 1. Since the reference product 060-120066 is the biggest/heaviest in the referenced product group, it represents a conservative scenario. This assumption is based on the mass and material composition.

Reference Service Life

For the purpose of this EPD the reference service life (RSL) of the product is considered to be 5 years. However, with the correct maintenance, the lifetime of the product can reach over 5 years.

Intended market

The intended market of this study is Sweden, and the baseline scenario involves the distribution, installation, and end-of-life in Sweden.

Overview of LCA Study

System boundaries

The results in this EPD are split into life cycle modules following EN 15804 (Figure 3): production (A1-A3), distribution (A4), (A5) installation, use (B6), and the end of the product's life (C1-C4). Module D represents environmental benefits and loads that occur beyond the system boundary (i.e., in future products).

Environmental Performance

This section presents the environmental performance of one unit of Pressure switch. Figure 4 presents the environmental impact of one Pressure switch 060-120066 across several environmental impact categories (following EN 15804+A2:2019) per life cycle stage, over its full 5-year life cycle, including Global Warming Potential.

Table 4: Environmental Impact Indicators

How to read scientific numbers:

e.g. 2,05E02 = 2,05 x 10² = 205

2,04E-01 = 2,04 x 10^-1 = 0,204

Table 5: Environmental impact indicator descriptions

Results for modules A1-A3 are specific to the product. All results from module A4 onwards should be considered as scenarios that represent one possible outcome. The true environmental performance of the product will depend on actual use.

The results in this section are relative expressions only and do not predict actual impacts, the exceeding of thresholds, safety margins, or risks. EPDs from others may not be comparable.

Carbon footprint

The total carbon footprint (GWPT), cradle-to-grave, of the product is 2.39E+00 kg CO2-eq (A1-C4). The carbon footprint (GWPT) of production of this product, cradle-to-gate, is 2.13E+00 kg CO2-eq (A1-A3).

*Disclaimer for ADPE, ADPF, WDP, ETPfw, HTPc, HTPnc, SQP: The results of these environmental impact indicators shall be used with care as the uncertainties on these results are high or as there is limited experience with the indicator.

**Disclaimer for ionizing radiation: This impact category deals mainly with the eventual impact of low dose ionizing radiation on the human health of the nuclear fuel cycle. It does not consider effects due to possible nuclear accidents, occupational exposure nor radioactive waste disposal in underground facilities. Potential ionizing radiation from the soil, from radon, and some construction materials is also not measured by this indicator.

Annex 1

How to read the table and determine the GWPT (Global Warming Potential Total)

1. Determine the code for identifying GWPT
2. Multiply the corresponding factor with the sum of values from A1-C4

Example:

Product Code: 060-519066

Conversion Factor : 0.662

GWPT A1-A3: 2.13E+00 KgCO2eq/ Pressure switch

Climate Change A1-A3 0.662 x 2.13E+00 KgCO2eq = 1.41E+00 KgCO2eq

GWPT A1-C4: 2.39E+00 kg CO2-eq/ Pressure switch

Climate Change A1-C4 0.662 x 2.39E+00 KgCO2eq = 1.58E+00 KgCO2eq

Table: GWPT values by Code

*Scaling factors were calculated by dividing the weight of each respective product by the weight of the heaviest item in the group.
